Mageia 2 technical spec #024 see also https://mageia.org/wiki/doku.php?id=iso2:technical_specification Currenctly, /etc/mtab is updated by mount and /sbin/mount.* . This does not always works reliably and requires all these programs to be setuid-root. Symlinking /etc/mtab to /proc/self/mounts which is maintained by the kernel provides a correct and up-to-date list of mounted filesystems to each running process (even in chroots). It allows removing the setuid bit of the mount helper programs, fixing bug #1157 . Systemd apparently requires /etc/mtab to be such a symlink. I have always symlinked /etc/mtab to /proc/mounts and never encountered any serious problem. This bug was reported on the setup package because it 'owns' /etc/mtab, but everything that must be fixed is probably in other packages.
