ldm - Lightweight Device Mounter
ldm [-d] [-u user] [-p path] [-c command] [-m mask] [-h]
ldm is a lightweight device mounter following the UNIX philosophy written in C and based on udev and libmount. The user can use umount to unmount the device or ldmc with the -r switch. The daemon can be controlled with the ldmc tool.
-
-d
Run ldm as a daemon.
-
-u user
Specify the user who owns the mountpoints.
-
-p path
Specify the base folder for the mount points. The default is /mnt.
-
-m fmask,dmask
Specify the fmask and dmask for the mounted devices in octal or symbolic format (eg. the octal mask 0777 is represented as rwxrwxrwx).
If only the fmask is specified then its used as umask and it's value is used as dmask too.
-
-c command
Specifies a command that is executed after a successful mount/unmount action. The following environment variables are defined :
-
LDM_MOUNTPOINT
The complete path to the mountpoint.
-
LDM_NODE
The path pointing to the device node in /dev
-
LDM_FS
The filesystem on the mounted device.
-
LDM_ACTION
The action ldm has just performed, it can either be mount, pre_unmount or unmount
-
-
-h
Print a brief help and exit.
ldm doesn't offer any blacklisting by itself but it honors the options found in the fstab so it will ignore any device with flag noauto.
The included systemd service expects a config file at /etc/ldm.conf similar to this:
MOUNT_OWNER=username
BASE_MOUNTPOINT=/mnt
FMASK_DMASK=fmask,dmask
EXTRA_ARGS=-c <path_to_executable>
The options FMASK_DMASK and EXTRA_ARGS are optional. The default value for FMASK_DMASK is 0133,0022. EXTRA_ARGS will be appended to the ldm executable.
ldmc(1), umount(8)
