Hm. This would have the disadvantage that every package that wants to be part of the "delete persistent infos" feature would have to add according checks in its file(s) instead of providing a central place via initramfs-tools. > but doesn't sound easy as i can see cases of netboot method, > where you clearly want persistent device naming. That's why I was thinking about adding support for BLACKLIST=y through /etc/initramfs-tools/initramfs.conf. As long as one doesn't explicitly enable BLACKLIST=y the behaviour is exactly as it was before. On the other hand everone suffering from the persistent files problem can get easily rid of it. regards, -mika-
