MOUNT_TFS(8) System Manager's Manual MOUNT_TFS(8)
mount_tfs, umount_tfs - mount and dismount TFS filesystems
/usr/etc/mount_tfs [ -r ] fs1 fs2 ... fsN dir
/usr/etc/mount -t tfs [ -o options ] fs dir
mount_tfs attaches a translucent file service (TFS) filesystem to the
directory dir. After the mount, the directory dir is a TFS directory
whose frontmost directory is fs1 and whose backmost directory is dir,
with any number of directories intervening. Effectively, the directo-
ries fs1 ... fsN are stacked in front of dir.)
TFS filesystems can also be mounted using the mount(8) command. The
mount command can only mount one directory, fs, in front of the back-
most directory, dir.
umount_tfs detaches the TFS filesystem rooted at dir. See tfs(4S) for
a description of a TFS filesystem.
-r Mount the TFS filesystem read-only.

mount_tfs will cause tfsd(8) to deadlock (hang and answer no more
requests) if it is used in conjunction with Network Software Environ-
ment (NSE) execsets. For example, a deadlock will occur if a user has
used mount_tfs to mount over /usr/lib, and then tries to activate an
NSE environment whose execset mounts over /usr/lib.
The directories fs1, fs2, ..., fsN must be writable.
