# /etc/mtab can be either a regular file updated by mount/umount, or a symlink
# to /proc/mounts.
#
# With linux < 2.6.26, /proc/mounts lacks information present in /etc/mtab such
# as additional mount options.  Thus a symlink breaks things like discquotas
# which rely on parsing the additional mount options.  As a result, we are
# mostly all still using it as a plain file.
#
# With linux >= 2.6.26, /proc/mounts contains all of the information in
# /etc/mtab, plus more.  The mount system call can now pass all of the mount
# options to the kernel, so no information is missing in /proc/mounts.  This
# has obviously useful benefits such as read-only root, and the state in
# /etc/mtab never gets out of sync with reality (there are a number of open
# bugs against mount where this occurs).
