Add config option for listing non-erasable packages

[Jan Rękorajski]

I just shoot myself in the foot twice today while uninstalling some libraries on PLD builders.
Poldek happily allowed and carried out uninstalation of rpm and itself.
Please add an option for listing essential, non-erasable packages - something like "hold" for upgrades.

echo rpm >> /etc/rpm/sysinfo/Requirename
echo poldek >> /etc/rpm/sysinfo/Requirename

works fine:

12:17:31 root[load: 0.01]@ppc rpm/sysinfo# chroot /pld
12:17:56 root[]@ppc /# echo rpm >> /etc/rpm/sysinfo/Requirename
12:17:59 root[]@ppc /# echo poldek >> /etc/rpm/sysinfo/Requirename
12:18:00 root[]@ppc /# poldek -e rpm
mark rpm-4.5-56

Thanks, didn't know about this one.

But still, it would be nice feature to be able to do it in poldek.conf
