TrueOS supported [[OpenZFS]] and the installer offered [[disk encryption]] with [[Geli (software)|geli]].

Development of TrueOS ended in 2020.<ref name="OS-Status"/>

== History ==
TrueOS was founded by FreeBSD professional Kris Moore in early 2005 as PC-BSD. In August 2006 it was voted the most beginner-friendly operating system by OSWeekly.com.<ref>{{cite web|url=http://www.osweekly.com/index.php?option=com_content&task=view&id=2287&Itemid=449|title=The Most Beginner Friendly OS|access-date=2006-08-10|url-status=dead|archive-url=https://web.archive.org/web/20061018194848/http://www.osweekly.com/index.php?option=com_content&task=view&id=2287&Itemid=449|archive-date=October 18, 2006 }}</ref>

The first beta of the PC-BSD consisted of only a GUI installer to get the user up and running with a FreeBSD 6 system with KDE3 pre-configured. This was a major innovation for the time as anyone wishing to install FreeBSD would have to manually tweak and run through a text installer. Kris Moore's goal was to make FreeBSD easy for everyone to use on the desktop and has since diverged even more in the direction of usability by including additional GUI administration tools and .pbi application installers. PC-BSD's application installer management involved a different approach to installing software than many other [[Unix-like]] operating systems, up to and including version 8.2, by means of the pbiDIR website.<ref>[https://web.archive.org/web/20130327233344/http://www.pbidir.com/ pbiDIR]</ref> Instead of using the [[FreeBSD Ports]] tree directly (although it remained available), PC-BSD used files with the ''.pbi'' [[filename extension]] (Push Button Installer) which, when double-clicked, brought up an installation [[wizard (software)|wizard]] program. An autobuild system tracked the FreeBSD ports collection and generated new .pbi files daily. All software packages and dependencies were installed from inside of the .pbi files into their own self-contained directories in ''/Programs''. This convention was aimed to decrease confusion about where binary programs reside, and to remove the possibility of a package breaking if system libraries are upgraded or changed, and to prevent [[dependency hell]].

On October 10, 2006, PC-BSD was acquired by enterprise hardware provider [[iXsystems]].<ref>{{cite web|url=http://www.ixsystems.com/resources/ix/news/ixsystems-announces-acquisition-of-pc-bsd-operating-system.html|title=iXsystems Announces Acquisition of PC-BSD Operating System|work=iXsystems.com|access-date=2011-06-29|archive-date=2013-09-25|archive-url=https://web.archive.org/web/20130925074819/http://www.ixsystems.com/resources/ix/news/ixsystems-announces-acquisition-of-pc-bsd-operating-system.html|url-status=dead}}</ref><ref>{{cite web|url=http://www.linux.com/archive/feature/57794?theme=print|title=Why iXsystems bought PC-BSD|author=Mayank Sharma|date=2006-10-13|work=linux.com|access-date=2010-04-01}}</ref> iXsystems employed Kris Moore as a full-time developer and leader of the project. In November 2007, iXsystems entered into a distribution agreement with [[Fry's Electronics]] whereby Fry's Electronics stores nationwide carry boxed copies of PC-BSD version 1.4 (Da Vinci Edition).<ref>{{cite web|url=http://www.ixsystems.com/resources/ix/news/ixsystems-announces-distribution-agreement-with-frys-electronics-for-pc-bsd.html|title=iXsystems Announces Distribution Agreement with Fry's Electronics|access-date=2011-06-29}}</ref> In January 2008, iXsystems entered into a similar agreement with [[Micro Center]].<ref>{{cite web|url=http://www.ixsystems.com/resources/ix/news/ixsystems-announces-distribution-agreement-with-micro-center-for-pc-bsd.html|title=iXsystems Announces Distribution Agreement with Micro Center for PC-BSD|access-date=2011-06-29}}</ref>

On September 1, 2016, the PC-BSD team announced that the name of the operating system would change to TrueOS.<ref name="TrueOS-Evolution" /> Along with the rebranding, the project also became a rolling release distribution, based on the FreeBSD-CURRENT branch.<ref name=":1">{{Cite web|url=http://bsd.slashdot.org/story/16/09/02/0350204/pc-bsd-follows-a-rolling-release-model-gets-renamed-to-trueos|title=PC-BSD Follows a Rolling Release Model, Gets Renamed To TrueOS - Slashdot|website=bsd.slashdot.org|date=2 September 2016 |access-date=2016-11-20}}</ref>

On November 15, 2016, TrueOS began the transition from FreeBSD's rc.d to [[OpenRC]] as the default init system. Apart from [[Gentoo/Alt]], where OpenRC was initially developed, this is the only other major BSD based operating system using OpenRC.

In July 2018, TrueOS announced that they would spin off the desktop edition into a separate project named ''Project Trident''.<ref>{{Cite web|url=https://itsfoss.com/project-trident-interview/|title = An Insight into the Future of TrueOS BSD and Project Trident - It's FOSS| date=21 August 2018 }}</ref><ref>{{Cite web|url=http://www.project-trident.org/|title=Home :: Project Trident|last=Trident|first=Project|website=www.project-trident.org|language=en|access-date=2018-10-24}}</ref>

Development of TrueOS ended in 2020 and the developers recommended users move to other BSD-based operating systems.<ref name="OS-Status"/>

Since version 7, PC-BSD began following the same numbering system as [[FreeBSD]].

Since version 9.0, the [[KDE Software Compilation 4|KDE SC]], customized to support tighter application integration and the .txz package management system, was no longer the only [[desktop environment]] supported by PC-BSD. While manual installation of other desktops such as [[Xfce]] and [[GNOME]] had been technically possible in earlier releases, none of these were supported in the earlier versions, and major functionality was lost when not using PC-BSD's special build of KDE SC.<ref name="pcbsdfaq">{{cite web|url=http://faqs.pcbsd.org/index.php?action=artikel&cat=8&id=334&artlang=en|title=Can I use Gnome with PC-BSD?|work=PC-BSD knowledge base|access-date=2009-03-05|url-status=dead|archive-url=https://web.archive.org/web/20100224185100/http://faqs.pcbsd.org/index.php?action=artikel&cat=8&id=334&artlang=en|archive-date=2010-02-24}}</ref> Starting with version 9.0, PC-BSD added other desktop environments, including GNOME, Xfce, [[LXDE]], and [[MATE (software)|MATE]].

PC-BSD used to support both [[amd64]] and [[i686]] architectures. Support for i686 was dropped in version 9.2.<ref>[http://ftp.pcbsd.org/pub/handbook/9.1/handbook_en_ver9.1.html#__RefHeading__20454_674241385 Minimum hardware requirements for PC-BSD 9.1]</ref><ref>[http://ftp.pcbsd.org/pub/handbook/9.2/pcbsd9.2_handbook_en_ver9.2.html#Minimum%20System%20Requirements Minimum hardware requirements for PC-BSD 9.2]</ref>

Three network interface widgets (2 [[Ethernet]] and 1 [[Wi-Fi]]) showing two network interfaces being up, one being down with no [[Ethernet physical layer|cable]] plugged in (hence: "no carrier").]]

Starting in September 2016 with the rebranding of PC-BSD, TrueOS became a rolling release distribution based on FreeBSD's current branch.<ref name="TrueOS-Evolution" /><ref name=":1" />

== Package management ==
TrueOS's [[package manager]] takes a similar approach to installing software to many other [[Unix-like]] operating systems. Instead of using the [[FreeBSD Ports]] tree directly (although it remains available), TrueOS uses files with the ''.txz'' [[filename extension]] packages which contain compiled ports. An autobuild system tracked the FreeBSD ports collection and generated new .txz files daily.

The TrueOS package management system aims to be visually similar to that of major operating systems such as [[Microsoft Windows]] and [[Apple Inc.|Apple]] [[macOS]], where applications are installed from a single download link with graphical prompts, while maintaining internally the traditional .txz package management systems that many Unix-like systems use.<ref>[https://web.archive.org/web/20161212161746/https://web.pcbsd.org/doc/11/html/introduction.html Introduction]</ref> The TrueOS package manager also takes care of creating categorized links in the KDE menu and on the KDE SC desktop.

== Lumina Desktop ==
In 2014, the PC-BSD project announced its development of a new [[desktop environment]], from scratch, named [[Lumina (desktop environment)|Lumina]]. Ken Moore is the main developer of Lumina, which is based on the [[Qt (software)|Qt]] toolkit.<ref>{{cite web|last=Larabel|first=Michael|title=PC-BSD Is Developing Its Own Desktop Environment|url=http://www.phoronix.com/scan.php?page=news_item&px=MTY3MTc|website=[[Phoronix]]|access-date=2 July 2014|date=23 April 2014}}</ref>

As of July 2016, Lumina has its own web site.<ref>{{cite news|last1=Larabel|first1=Michael|title=PC-BSD's Lumina Desktop Now In Beta For v1.0|url=http://www.phoronix.com/scan.php?page=news_item&px=Lumina-1.0-Beta|website=[[Phoronix]]|access-date=4 July 2016|date=4 July 2016|publisher=Phoronix}}</ref>

The desktop environment is not an application development toolkit, and aims to be a graphical interface that only uses plugins for customization.<ref name="Exploring and sharing Lumina">{{cite web|title=Exploring and sharing Lumina|url=http://lumina-desktop.org/|website=Lumina Desktop Environment|access-date=4 July 2016}}</ref>

== License ==
TrueOS was originally licensed under the [[GNU General Public License]] (GPL) because the developers were under the impression that applications using the [[Qt (software)|Qt]], which TrueOS uses for its interface development, must be licensed under the GPL or the [[Q Public License]]. Upon discovering that there was, in fact, no such restriction, the TrueOS developers later [[Software relicensing|relicensed]] the code under a BSD-like 3-clause license.<ref name=PC-BSD-License>{{cite web|title=Press And Legal - Legal notices|url=http://wiki.pcbsd.org/index.php/Press_And_Legal|website=wiki.pcbsd.org|publisher=The PC‑BSD Project|access-date=2 March 2015}}</ref>

== Hardware requirements ==
The New York City *BSD User Group runs a service named dmesgd,<ref>[http://dmesgd.nycbug.org/index.cgi?action=dmesgd&do=index&fts=FreeBSD ''dmesgd'']</ref> which provides user-submitted [[dmesg]] information for different computer hardware ([[laptop]]s, [[workstation]]s, [[single-board computer]]s, [[embedded system]]s, [[virtual machine]]s, etc.) capable of running TrueOS.

According to the TrueOS wiki,<ref>{{cite web|url=http://www.trueos.org/handbook/preinstall.html#minimum-requirements|title=Hardware requirements on TrueOS wiki.}}</ref> TrueOS has the following hardware requirements:

===Minimum===
*[[amd64]] processor
*1 GiB of [[Random-access memory|RAM]]
*20 GiB free [[Data storage device|hard drive]] space
*Network card

===Recommended===
*amd64 processor
*[[EFI system partition]] for installation of [[rEFInd]]
*4 GiB of RAM
*30 GiB of free hard drive space on a [[Disk partitioning|primary partition]] for a [[desktop environment|desktop]] installation, or 20 GiB for a [[server (computing)|server]] installation
**50 GiB is recommended for installations with [[backup]] services
*3D accelerated video card
*Network card
*Sound card

=== UEFI ===
[[UEFI]] support (for [[amd64]] only) has been added to the installer and the boot manager since version 10.1 with the default EFI boot manager to be [[rEFInd]].<ref>{{cite web|url=http://wiki.pcbsd.org/index.php/What%27s_New/10.1|title=What's New in 10.1}}</ref> This includes [[Advanced Configuration and Power Interface|ACPI]] detection and setup of Root System Description Pointer (RSDP),<ref>[http://wiki.osdev.org/RSDP RSDP]</ref> eXtended System Descriptor Table (XSDT),<ref>[http://wiki.osdev.org/XSDT XSDT]</ref> and Root System Description Table (RSDT)<ref>[http://wiki.osdev.org/RSDT RSDT]</ref> pass-through values to the [[kernel (operating system)|kernel]]. A new installation is needed in order to install UEFI support as it requires the creation of a small [[File Allocation Table|FAT]] partition. The current UEFI does not support secure boot.
