AUTOFS(5) FreeBSD File Formats Manual AUTOFS(5)
NAME autofs - automounter filesystem
SYNOPSIS To compile this driver into the kernel, place the following line in the kernel configuration file:
options AUTOFS
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
autofs_load="YES"
DESCRIPTION The autofs driver is the kernel component of the automounter infrastructure. Its job is to pass mount requests to the automountd(8) daemon, and pause the processes trying to access the automounted filesystem until the mount is completed. It is mounted by the automount(8).
OPTIONS These options are available when mounting autofs file systems:
master_options Mount options for all filesystems specified in the map entry.
master_prefix Filesystem mountpoint prefix.
SYSCTL VARIABLES The following variables are available as both sysctl(8) variables and loader(8) tunables:
vfs.autofs.debug Verbosity level for log messages from the autofs driver. Set to 0 to disable logging or 1 to warn about potential problems. Larger values enable debugging output. Defaults to 1.
vfs.autofs.interruptible Set to 1 to allow mount requests to be interrupted by signal. Defaults to 1.
vfs.autofs.retry_delay Number of seconds before retrying mount requests. Defaults to 1.
vfs.autofs.retry_attempts Number of attempts before failing mount. Defaults to 3.
vfs.autofs.cache Number of seconds to wait before reinvoking automountd(8) for any given file or directory. Defaults to 600.
vfs.autofs.timeout Number of seconds to wait for automountd(8) to handle the mount request. Defaults to 30.
umount -At autofs
To mount autofs filesystems specified in auto_master(5):
automount
