It is not possible to set the files ystem in /proc/mounts as it is
possible with /etc/mtab. This breaks the usage of mount helper tools
like mount.crypt from pam_mount that allows to mount and umount
encrypted partitions using mount. To get umount.crypt called when umount
of an encrypted file system is run, crypt needs to be written in
the file system column in /etc/mtab.
