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.
Run ldm as a daemon.
Specify the user who owns the mountpoints.
Specify the base folder for the mount points. The default is /mnt.
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.
Specifies a command that is executed after a successful mount/unmount action. The following environment variables are defined :
The complete path to the mountpoint.
The path pointing to the device node in /dev
The filesystem on the mounted device.
The action ldm has just performed, it can either be mount, pre_unmount or unmount
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.
