[pbs-devel] [PATCH proxmox-backup 08/15] pbs: add mount-removable command to commandSocket

[Hannes Laimer <h.laimer@proxmox.com>]

Adds 'mount-removable' command to superuser commandSocket, this command
is needed for automatic mountntig of removable datastores. When udev
rules are executed, the process and whatever is forked from it will be
killed almost immediately, therefore the mounting has to done
asynchronously.
