AUTOMOUNT is a devd(8) based automounter for FreeBSD.
It supports following file systems:
UFS/FAT/exFAT/NTFS/EXT2/EXT3/EXT4
It needs these ports to mount NTFS/exFAT/EXT4 respectively:
o sysutils/fusefs-ntfs
o sysutils/fusefs-exfat
o sysutils/fusefs-ext4fuse
By default it mounts/unmounts all removable media but
it is possible to set some additional options at the
/usr/local/etc/automount.conf config file.
Below is a list of possible options with description.
MNTPREFIX (set to /media by default)
With this options You can alter the default root
for mounting the removable media, for example to
the /mnt directory.
example: MNTPREFIX="/media"
ENCODING (set to en_US.ISO8859-1 by default)
Only used with FAT32 mounts, specifies which
encoding to use at the mount.
example: ENCODING="pl_PL.ISO8859-2"
CODEPAGE (set to cp437 by default)
Only used with FAT32 mounts, specifies which
code page to use at the mount.
example: CODEPAGE="cp852"
USER (unset by default)
If set to some username, the mount command will
chown(1) the mount directory with the user and
its primary user group. If used with FM option
allows to launch the specified file manager after
a successful mount.
example: USER="vermaden"
FM (unset by default)
If set to file manager command, the mount will
launch the specified command after successful
mount. Works only if USER parameter is also set.
example: FM="nautilus --browser --no-desktop"
USERUMOUNT (set to NO by default)
When set to YES it will 'chmod +s /sbin/umount'
which would allow an USER to unmount the file
system with their selected file manager.
example: USERUMOUNT="YES"
ATIME (set to YES by default)
When set to NO it will mount filesystems with
noatime options when possible.
example: ATIME="NO"
REMOVEDIRS (set to NO by default)
When set to YES it will remove empty directories
under the used ${MNTPREFIX} after device detach.
example: REMOVEDIRS="YES"
BLACKLIST (unset by default)
The automount will ignore devices defined here.
example: BLACKLIST="da0 da3s1a"
TIMEOUT (set to 8 by default)
Do not wait longer then the specified timeout for
the device node to appear in /dev and be accessible.
example: TIMEOUT="8"
DELAY (set to 1 second by default)
How often to check for device availability.
example: DELAY="2.5"
BOOTDELAY (set to 45 seconds by default)
How long to wait for boot process to complete.
example: BOOTDELAY="30"
