A lightweight device mounter, with libudev as only dependency

NAME

ldm - Lightweight Device Mounter

SYNOPSIS

ldm [-d] [-u user] [-p path] [-c command] [-m mask] [-h]

DESCRIPTION

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.

OPTIONS

• -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.

BLACKLISTING

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.

INSTALL

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.
