(Sorry for the inconvenience)
Les caractéristiques suivantes ont été ajoutées ou améliorées pour PC-BSD® 9.2:
- Basé sur FreeBSD 9.2-RELEASE qui ajoute cette [NO URL YET liste des fonctionnalités].
- Utilise ZFSv5000 (drapeaux de fond), la dernière version open source de ZFS. Cette version inclut l'algorithme de compression LZ4.
- PC-BSD® est seulement disponible sur les systèmes 64 bits et l'installateur graphique permet de formater le(s) disque(s) sélectionné(s) ou une partition comme ZFS. Cela signifie que les images ne sont plus fournis pour les systèmes 32 bits et que l'installateur graphique ne fournit plus une option au format avec UFS.
- GRUB est utilisé pour fournir le menu de démarrage graphique. Il fournit un support pour multiple boot environments, consoles de série, démarrage GPT, UEFI, les graphiques et un chargement plus rapide des modules du noyau. Lors de l'installation, la plupart des autres systèmes d'exploitation existants seront automatiquement ajoutés dans le menu de démarrage.
- The system has changed from the traditional ports system to pkgng and all of the PC-BSD® utilities that deal with installing or updating software use pkgng. This means that you can safely install non-PBI software from the command line and that a system upgrade will no longer delete non-PBI software.
- The pkgng repository used by the software installed with the operating system is updated on or about the 5th and 20th of each month and a new freebsd-update patch is released on the 1st of each month.
- The PC-BSD® utilities that deal with installing software or updates use which greatly increases download speed over slow links. aria2 achieves this by downloading a file from multiple sources over multiple protocols in order to utilize the maximum download bandwidth. The pc-pkg command has been added as a wrapper script to pkg. Use pc-pkg if you wish to increase your download speed when installing or upgrading pkgng packages.
- PC-BSD® uses a Content Delivery Network (CDN) service for its network backbone. This means that users no longer have to pick a mirror close to their geographical location in order to get decent download speeds when downloading PC-BSD, updates, or software. It will also prevent failed updates as it removes the possibility of a mirror being out of date or offline.
- The source code repository for PC-BSD® has changed to . Instructions for obtaining the source code using git can be found on .
- The installer provides a built-in status tip bar, instead of tooltips, to display text about the moused-over widget.
- If a non-English language is selected during installation, the post-installation configuration screens will automatically be displayed in the selected language. Additionally, if the user installed the KDE window manager, KDE-L10N will be installed.
- The initial installation screen provides an option to load a saved installation configuration file from a FAT-formatted USB stick.
- The installer provides an option to install a Desktop or a Server. If you select to Install a Server, it will install TrueOS®, a command-line version of FreeBSD which adds the command-line versions of the PC-BSD® utilities.
- The installer provides an option to restore or clone the operating system from a remote snapshot created with Life Preserver. A network configuration icon is included to configure the connection to the server containing the remote snapshot.
- The Advanced Mode screen provides configurable options to force 4K sector size, install GRUB, and set the ZFS pool name.
- The installation summary screen provides an option to save configuration of the current installation selections to a FAT-formatted USB stick so that it can be re-used at a later time.
- The PEFS encryption system has replaced the GELI encryption system. PEFS offers several benefits over GELI. Rather than encrypting the entire disk(s), which may expose too much known cryptographic data, it can be used on a per-user basis to encrypt that user's home directory. When the user logs in, their home directory is automatically decrypted and it is again encrypted when the user logs out. PEFS supports hardware acceleration. It can also be used to encrypt other directories using the command line; read man pefs for examples.
- The encryption option has been removed from the installer and has been replaced by a "Encrypt user files" checkbox in the post-installation Create a User Screen for the primary login account and in the User Manager utility for creating additional user accounts. If you choose to use PEFS, it is very important to select a good password that you will not forget. At this time, the password cannot be easily changed as it is associated with the encryption key. A future version of PC-BSD® will provide a utility for managing encryption keys. In the mean time, this forum post provides a work around if you need to change a password of a user that is using PEFS.
- It is possible to easily Convert a FreeBSD System to PC-BSD®/9.2.
- When administrative access is needed, the user will be prompted for their own password. This means that users do not have to know the root password. Any user which is a member of the wheel group will have the ability to gain administrative access. By default, the only user in this group is the user account that you create during post-installation configuration. If additional users need this ability, use the Groups tab of User Manager to add them to the wheel group.
- AppCafe® has been re-designed with a cleaner code base. New features include the ability to perform actions on multiple applications, save downloaded .pbi files to a specified directory, downgrade installed software if an earlier version is available as a PBI, the ability to import and export PBI lists, and improved search ability.
- EasyPBI has been revamped as version 2, making it even easier to create PBIs.
- A graphical Boot Manager utility for managing boot environments and the GRUB configuration has been added to Control Panel.
- The mirrors tab of System Manager has been removed as downloads are provided through a CDN.
- The system packages tab has been removed from System Manager as this functionality is provided in Package Manager.
- The boot screen section has been removed from System Manager.
- The Mount Tray interface and detection algorithm has been improved. It can also mount an ISO to a memory disk.
- The Life Preserver utility has been completely rewritten. It allows you to schedule the creation of local ZFS snapshots and provides a built-in browser for finding previous versions of files and restoring them. It includes optional support for replicating the snapshots to a remote system, such as FreeNAS. A remote snapshot can be used to restore the operating system if disaster recovery is required.
- Many improvements to [[Warden®/9.2/en|Translations:Warden®/9.2/Page display title/en]] including the ability to create jails by hostname instead of by IP address, jail IP addresses can be changed after jail creation, vimage can be enabled/disabled on a per-jail basis, IPv4 or IPv6 addressing can be enabled or disabled, aliases can be added on a per-jail basis, and jail sysctls can be easily enabled on a per-jail basis.
- A Template Manager has been added to Warden®. Templates can be added then used to create a new jail. For example, templates can be used to install different versions of FreeBSD and have been tested from FreeBSD 4.1.1 to FreeBSD-CURRENT.
- The ability to use an external DHCP server has been added to Thin Client/9.2 and the ports collection is no longer a requirement for using this script.
- The system uses /etc/rc.conf.pcbsd as the default, desktop operating system version of the RC configuration file. The server operating system version of this file is called /etc/rc.conf.trueos. Do not make any changes to either of these files. Instead, make any needed customizations to /etc/rc.conf. This way, when the system is upgraded, changes to the default configuration file will not affect any settings and overrides which have been placed into /etc/rc.conf.
- The default wallpaper has been updated and 9.2 is referred to as PC-BSD® Isotope Infusion to differentiate it from 9.1.
- The graphical command has been added to PC-BSD® and the command line equivalent smartctl has been added to both PC-BSD® and TrueOS®. These utilities can be used to inspect and test the system's -capable hard drives to determine their health.
- Mosh has been added to base to provide an SSH replacement over intermittent links.
- has been added to base which should prevent kernel module mis-matches. The installation includes the . If you are currently using the VirtualBox PBI, you should uninstall it.
