AUTOUNMOUNTD(8)             System Manager's Manual            AUTOUNMOUNTD(8)

NAME
     autounmountd - daemon unmounting automounted file systems

SYNOPSIS
     autounmountd [-r time] [-t time] [-dv]

DESCRIPTION
     The autounmountd daemon is responsible for unmounting file systems
     mounted by automountd(8).  On startup, autounmountd retrieves a list of
     file systems that have the automounted mount option set.  The list is
     updated every time a file system is mounted or unmounted.  After a
     specified time passes, autounmountd attempts to unmount a file system,
     retrying after some time if necessary.

     These options are available:

     -d     Debug mode: increase verbosity and do not daemonize.

     -r     Number of seconds to wait before trying to unmount an expired file
            system after a previous attempt failed, possibly due to file
            system being busy.  The default value is 600, or ten minutes.

     -t     Number of seconds to wait before trying to unmount a file system.
            The default value is 600, or ten minutes.

     -v     Increase verbosity.

EXIT STATUS
     The autounmountd utility exits 0 on success, and >0 if an error occurs.
