Restoring perms
And so there was this guy who performed a chmod -R 770 /. That's funny, but what to do when you have to repair the machine ? You can extract all the original permissions from the RPM database :
#!/usr/bin/perl
use strict;
use URPM;
URPM::DB::open()->traverse(sub {
my ($package) = @_;
my $name = $package->fullname;
my @modes = $package->files_mode;
printf "$name:$_:%04o\n",(shift @modes) & 07777 for $package->files;
});
At least this works on a Mandrakelinux system. URPM.pm, the perl bindings to RPMs, are not backported to CPAN (-- yet).

Hope you are taking this the next step and automating the setting of these permissions.
It would take quite a long time to do them manually...

Good thing I don't need any exercise!
