Linux, politics, and other interesting things
I have written a script for Debian named selinux-activate which is included in selinux-basics version 0.3.3+nmu1 (which I have uploaded to Debian/Unstable). The script when run with no parameters will change the GRUB configuration to include selinux=1 on the kernel command-line and enable SE Linux support in the PAM modules for login, gdm, and kdm. One issue with this is that if you run the command before installing kdm or gdm then you won’t have the pam configuration changed – but as it’s OK to run the script multiple times this shouldn’t be a problem.
The new selinux-basics package will also force a reboot after relabelling all filesystems. I had tested “umount -a ; reboot -f” but discovered that “reboot -f” causes filesystem corruption in some situations (my EeePC running an encrypted LVM volume on an SD card had this problem). So I now use a regular “reboot“.
If no-one points out any serious flaws I plan to ask the release team to include this version of selinux-basics in Lenny. I believe that it will make it significantly easier to install SE Linux while also reducing the incidence of systems being damaged due to mistakes. If you edit the GRUB configuration file by hand then there is a risk of a typo making a system unbootable.
The package in question is already in my Lenny repository, see my previous post about Lenny SE Linux for details .Debian, Most Popular, Selinux
