In /etc/sudoers.d/ create a file 001 (if it doesn't exist).Install sys-apps/pmount and app-admin/sudo, if they have not been installed yet.Regular user accounts that need to access FAT-formatted USB keys must be added to group 'plugdev'.

This page assumes a Linux distro using busybox's mdev device manager as described in the mdev page.Keeping mdev-related scripts in the same area makes things easier to keep track of. Why is the main automount script under /lib/mdev?īecause that's where mdev already puts some scripts under Gentoo.

There may be lightweight distros that do not have bash loaded. Although this is currently implemented on Gentoo Linux, it is hopefully portable to other Linux distros, and embedded systems. If a machine is running mdev as the device manager, it's guaranteed to have busybox present.

Why are scripts launched with #!/bin/busybox ash rather than #!/bin/bash?.

It would require a change to the source code of pmount to use a different directory. This is a security feature, in that it won't unmount devices whose directories are not in the /media directory.īecause pmount is currently hard-coded to automount in /media.

pumount (pmount's version of 'umount') is restricted to acting in the /media directory.

That functionality has not yet been implemented in this work, but using pmount leaves the door open to doing so later.

pmount optionally supports assigning a user-selected name to the mounted directory, similar to 'writing udev rules'.

pmount supports mounting FAT-based filesystems with desired permissions and assigns user root and group plugdev.
