figure out how to enable mounts for unprivileged users. (Why don't we
just explain vfs.generic.usermount in the mount(8) man page?)
Also add another example of different ways in which the "special"
argument is interpreted by different file systems: mount_tmpfs(8)
ignores it.
was deleted from the filesystem to the disk driver, commonly
known as "discard" or "trim".
fs/driver support is in ffs and ata wd for now.
This is what was posted here:

with minor cleanup, and the global switch replaced by a mount option.
for UFS1).
Remove kernel option for EA backing store autocreation and do it by
default. Add a sysctl so that autocreated attriutr size can be modified.
the following work:
mount -t tmpfs -o union tmpfs /
(some caveats are implied, such as if you "mkdir /usr" you're
screwed, but then again you'll get there with "rm -rf /usr" even
without union -- we supply rope)

* Say that the "nfs" inference is deprecated. (It was deprecated in
revision 1.87 of mount.c, dated 2009-01-11.)
* Add "-t nfs" in an example, so as not to rely on the automatic
inference of nfs when the path contains a colon.
* Try to improve the description of how the arguments are interpreted.
Use this routine both in mount_fs and rump_fs to provide equivalent
command line parameters and therefore usage interchangeability.
While doing this, combine some common mountgoop to mountprog.h
