mount_mfs(8); the mount_*(8) are hardlinked to mount (appropriate mount routine
is called depending on program name) - this saves approx. 1.7MB of /sbin
space
mount.c: make all local symbols static
that require all of /sbin/mount_* and /sbin/umount to be modified:
* incorporate vfslist.c, adding checkvfsname() and makevfslist()
* getmntopts() now takes 4 args (adding int *altflagp)
types. when using mount(8) with '-a', do _NOT_ remount file systems
that have been mounted once already. (This cannot be 100% precisely
determined (thanks to mfs, union fs, and similar file systems which
don't use a 'real' mounted-from node), and changed options cannot be updated
with mount -a. however, options wouldn't be updated with the old mount -a
anyway, and this solves several annoyances.
