DeepFreezeLinuxOverview
AboutDeepFreeze
Deep Freeze Linux provides a completely non-restrictive working environment where there is no
need to be concerned about system damage or corruption; a simple restart eradicates all changes and
ensures that the standard system conguration is available at all times. All changes to a machine are
temporary for that working session. e need for IT professionals to perform rebuilds, re-image, or
troubleshoot computers is eliminated, resulting in a reduction in IT expenditures and an increase in
computer uptime.
SystemRequirements
Deep Freeze Linux requires SLED (SuSE Linux Enterprise Desktop) 10 with the ext2 or ext3 le system
running on IDE and SATA hard drives, and the KDE or GNOME desktop environments.
e minimum hardware requirement is 128 MB RAM, 20GB hard drive, and a 1.5 GHz processor.
ImportantTerminology
A Frozen partition is completely restored to its exact original conguration and contents upon each
restart of the machine.
A awed partition functions normally, as if Deep Freeze was not installed.

DeployingDeepFreeze
Installation and conguration of Deep Freeze Linux requires administrative access. Installs, uninstalls,
and conguration changes require a restart to take eect.
Deep Freeze Linux is distributed on a CD-ROM in a media package, or as a downloadable le via the
Internet.
InstallingDeepFreeze
To install Deep Freeze Linux from the command-line:
1. In a terminal window, with root-user privileges, enter the following:
sudo rpm -i <DeepFreezeLinux.rpm>
2. Press Enter.
Note that <DeepFreezeLinux.rpm> must be replaced with the exact name of the rpm le
for the version of Deep Freeze Linux that is being installed.
To install Deep Freeze Linux graphically:
1. With root-user privileges, double-click <DeepFreezeLinux.rpm> in a graphical window (e.g.
in Konqueror).
2. Follow any prompts.
Upon completion of a successful installation and aer the computer has been restarted, Deep Freeze
is automatically congured to put all partitions into a Frozen state. Partitions that are to be put in a
awed state can be specied aer the install.
Alternatively, Deep Freeze Linux can be installed using YaST. Refer to the YaST documentation for
instructions on how to do this.
Aer installation has completed, the Deep Freeze Linux application (d) will be installed in /opt/d
and a so-link of /sbin/d will be created. e $PATH and $MANPATH variables can optionally be
updated to provide specic users with access to the Deep Freeze Linux application (e.g. the root-user).
is oen requires updating the appropriate .bashrc le.
UninstallingDeepFreeze
To uninstall Deep Freeze Linux from the command-line:
1. In a terminal window, with root-user privileges, enter the following:
sudo rpm -e <DeepFreezeLinux.rpm>
2. Press Enter:
Note that <DeepFreezeLinux.rpm> must be replaced with the exact name of the rpm le
for the version of Deep Freeze Linux that is being installed.
To uninstall Deep Freeze Linux graphically:
1. With root-user privileges, launch the application used to manage application installation and
removal.
2. Select the Deep Freeze Linux application and follow the usual procedure for removing the
application.
Alternatively, Deep Freeze Linux can be uninstalled using YaST. Refer to the YaST documentation for
instructions on how to do this.

ConguringDeepFreeze
If all partitions are Frozen on a machine, a user can create, save, change, and delete les. However, all
changes are temporary, unless a awed partition is being utilized. e complete contents of a Frozen
partition are restored at restart.
All changes made in Deep Freeze only take eect aer a restart.
LaunchingDeepFreeze
To launch Deep Freeze, click the Deep Freeze icon in the kicker panel and select Congure Deep
Freeze:
Alternatively, enter su -c “dfl -g” in a terminal window and press Enter.
Deep Freeze appears, with two tabs: Boot Control and Partitions. On all tabs, the OK button saves and
closes the Main Screen; the Apply button saves any changes but does not close the Main Screen; the
Cancel button closes the Main Screen, but displays a warning prompting the user to save any unsaved
changes (if they exist) prior to doing so.
BootControlTab
Deep Freeze appears with the Boot Control tab selected.
e Boot Control tab contains radio buttons used to change the status of Deep Freeze on a machine:
• To set the machine to a Frozen state, choose Boot Frozen
• To set the machine to a awed state for a specied number of restarts, choose Boot awed on
next and specify the number of restarts (the number entered must be between 1-99)
• To set the machine to a awed state, choose Boot awed

10
To restart the machine aer making changes, click Restart.
e following conguration options are available:
• To hide the Frozen icon, check the Hide “Frozen” Icon in Kicker Panel checkbox
• To hide the awed icon, check the Hide “awed” Icon in Kicker Panel checkbox
PartitionsTab
When the Partitions tab is selected, Deep Freeze searches the machine and lists the supported partitions
present on a machine. e partitions listed can be put into a Frozen state or a awed state.
All partitions on the machine are initially Frozen by default.
To aw a partition, uncheck the corresponding box in the Frozen? column.
To Freeze a partition, check the corresponding box in the Frozen? column.
Removable media such as external FireWire or USB hard drives or keychain drives are
not displayed and cannot be Frozen.
ExportingandImportingCongurations
A le containing the conguration information set in Deep Freeze can be exported to an XML le. e
resulting XML le can be imported into Deep Freeze on the same or alternate computers.
To export the conguration information, click Export and save the le to a preferred location.
To import a conguration le, click Import and browse to the location of the saved le. e computer
must be restarted for any changes to take eect from the imported le.
