To make a 'clean' system disk that can be put into another system, remove all the /etc/udev/rules.d/*persistant* and /etc/sysconfig/network-scripts/*eth? and /etc/sysconfig/network-scripts/*wlan? and /etc/X11/xorg.conf files.
I copied the partition to another disk, and put that to a new computer, installed grub and moved /etc/udev/rules.d/*persistent* and /etc/sysconfig/network-scripts/*eth? to /root/backups.
The system boots and seems to work, but there are no new /etc/udev/rules.d/*persistent* files, should there be?
Are the /etc/udev/rules.d/*persistent* needed? Even if those are not required can I somehow re-create those?
I do have the old ones, but I would not like to use those, I'd rather make/generate new ones if possible (and needed).
