EXTERNAL INFLUENCES — Automounter
Environment Variables
Environment variables can be used within an automount
map. For example, if $HOME appears within a
map,
automount expands it to the current value of the
HOME environment variable.
To protect a reference from neighboring characters, surround the variable name with braces (
{}).
Environment variables cannot appear as a key entry in maps.
WARNINGS — Automounter
Do not send the
SIGKILL signal (kill -9
,orkill -KILL) to the automount daemon. Doing so
causes any processes accessing mount directories served by
automount to hang. A system reboot may be
required to recover from this state.
Do not start an
automount daemon while another is still running. If restarting
automount, make sure
the first daemon and all of its children are not running.
When
automount receives signal SIGHUP, it rereads the
/etc/mnttab file to update its internal
record of currently mounted file systems. If a file system mounted by
automount is unmounted by a
umount command, automount should be forced to reread the file by sending the SIGHUP signal (see
kill(1)).
Shell file name expansion does not apply to objects not currently mounted.
Since
automount is single-threaded, any request that is delayed by a slow or nonresponding NFS server
delays all subsequent automatic mount requests until it completes.
Programs that read /etc/mnttab and then touch files that reside under automatic mount points intro-
duce further entries to the file.
Automatically-mounted file systems are mounted with type
ignore; they do not appear in the output of
either
mount or bdf (see mount(1M) and bdf(1M)).
