I'd suggest using LIDS for such things. For those who don't know it, it's a kernel patch which adds capabilities support. It makes impossible to delete logs 'cause in order to disable "append only" you should reboot with a kernel without lids, but lids forbids rebooting unless the admin is logged from a local console. -- Luca Gibelli (firstname.lastname@example.org || email@example.com) PGP Fingerprint: EC7C D6D2 D754 89F8 BDE8 8924 6341 3B07 C2F3 9102 PGP Key Available on: Key Servers || http://gibelli.oltrelinux.com/gibelli.asc BOFH excuse 208: Traffic jam on the Information Superhighway.
