Restoring perms

[ #19651 ]
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).
