It needs to be replaced by a symlink to /proc/self/mounts. With todays setups, mirroring volatile kernel state in a regular file in the filesystem can not work reliably. There are a few uncommon features missing without /etc/mtab, and util-linux is currently working on moving the information which is not available from the kernel, like 'user umounts' to a private file which can't be read by other applications than mount. We will need to find out which package will create the /etc/mtab symlink now. As a first step /etc/init.d/boot.rootfsck needs to stop deleting a /etc/mtab, if it's a symlink. /etc/init.d/boot.rootfsck is not used when systemd boots the box, but any sysv bootup will delete this valid setup. Ruediger, could you please get rid of the rm? Thanks. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
