If several of the -a, -l or -n options are invoked (or their long forms, respectively --always, --lockfs
or --nolockfs), the last overrides the previous ones. The invocation of these options also overrides the
variable 'BILIBOP_LOCKFS_NOTIFY_POLICY' that can be set in bilibop.conf(5).
-a, --always
Always send a notification: about filesystems on which permanent changes are allowed, and about
filesystems on which temporary changes are allowed. So, if the bilibop-lockfs feature is enabled,
and one or more mountpoints have been whitelisted in /etc/bilibop/bilibop.conf, then two
notifications are send to the user.
-h, --help
Print a short help message on stdout and exit.
-l, --lockfs
Send a notification only about filesystems for which the 'lockfs' feature has been enabled, i.e.
about mountpoints for which only temporary changes are allowed. All these changes will be lost at
next shutdown of the computer.
-n, --nolockfs
Send a notification only about filesystems for which the 'lockfs' feature has been disabled, i.e.
about mountpoints for which permanent changes are allowed. All these changes will be kept after
the shutdown of the computer.
-tTIME, --expire-time=TIME
Specifies the timeout in milliseconds at which to expire the notification. Values of TIME less
than '1000' (1 second) make the timeout is disabled and the notification never expires. If TIME
is not an integer, this option is silently ignored.
