33.Sh NAME
34.Nm automountd
35.Nd daemon handling autofs mount requests

37.Nm

44.Sh DESCRIPTION
45The
46.Nm
47daemon is responsible for handling
48.Xr autofs 5
49mount requests, parsing maps,
50and mounting filesystems they specify.
51On startup,
52.Nm
53forks into background and waits for kernel requests.
54When a request is received,
55.Nm
56forks a child process.
57The child process parses the appropriate map and mounts filesystems accordingly.
58Then it signals the kernel to release blocked processes that were waiting
59for the mount.
60.Bl -tag -width ".Fl v"
61.It Fl D
62Define a variable.
63.It Fl i
64For indirect mounts, only create subdirectories if there are no wildcard
65entries.
66Without
67.Fl i ,
68.Nm
69creates all the subdirectories it can.
70Users may not realize that the wildcard map entry makes it possible to access
71directories that have not yet been created.
72.It Fl m Ar maxproc
73Limit the number of forked
74.Nm
75processes, and thus the number of mount requests being handled in parallel.
76The default is 30.
77.It Fl d
78Debug mode: increase verbosity and do not daemonize.
79.It Fl o Ar options
80Specify mount options.
81Options specified here will be overridden by options entered in maps or
82.Xr auto_master 5 .
83.It Fl v
84Increase verbosity.
