were these mount types left out of the output of mount for a reason?
just curious.

Mount uses /etc/mtab - it is possible to mount file systems without
writing to mtab. Also, the file systems mounted before the root file
system is remounted r/w will not get written. On the other hand,
/proc/mounts shows all the mounts the kernel knows about.
I suspect the reason that mount does not use /proc/mounts is for a
couple of reasons. First of all, when it was written, there was not a
/proc file system. I believe you can also run a Linux system without a
/proc file system.

Isn't it possible to make /etc/mtab a link to /proc/mounts? I seem to
remember that some distos do this.
