/etc/mtab is a file on the filesystem.

/proc/mounts is a query to the kernel.

When no arguments are given to mount(8) it reads from /etc/mtab, which
is maintained by the same program when filesystems are mounted.

When a filesystem is mounted using --no-mtab, the /etc/mtab file won't
be updated.

/proc/mounts seems most reliable.

/etc/mtab seems to omit several filesystems.  It might have something to
do with /etc not being available at the time that some filesystems
become available.
