package dmsetup tags 501736 + wontfix thanks On Thu, Oct 09, 2008 at 11:30:18PM +0200, Mario 'BitKoenig' Holbe wrote: > This can be suppressed by telling udev a different device NAME, in which > case findfs returns the descriptive node. ... > Perhaps... for backward compatibility one could additionally > SYMLINK+="%k". Don't know if this is really needed, since the dm-<minor>
Oups, at least lilo depends on the /dev/dm-<minor> link because it's referenced in /proc/partitions. And with the symlink in place, findfs returns /dev/dm-<minor> again, *sigh*.
