The daemon can be configured by passing different command line arguments to it.
The arguments are:
* `SNAPSHOTS_DIR`
This argument specifies the path where grub-btrfsd looks for newly created snapshots and snapshot deletions. It is usually defined by the program used to make snapshots.
E.g. for Snapper this would be `/.snapshots`
* `SNAPSHOTS_DIRS`
This argument specifies the (space separated) paths where grub-btrfsd looks for newly created snapshots and snapshot deletions. It is usually defined by the program used to make snapshots.
E.g. for Snapper this would be `/.snapshots`. It is possible to define more than one directory here, all directories will inherit the same settings (recursive etc.).
This argument is not necessary to provide if `--timeshift-auto` is set.
* `-c / --no-color`
Disable colors in output.
* `-l / --log-file`
@@ -109,7 +110,7 @@ Watch the snapshots directory recursively
* `-o / --timeshift-old`
Look for snapshots in `/run/timeshift/backup/timeshift-btrfs` instead of `/run/timeshift/$PID/backup/timeshift-btrfs.` This is to be used for Timeshift versions <22.06.
* `-t / --timeshift-auto`
This is a flag to activate the auto detection of the path where Timeshift stores snapshots. Newer versions (>=22.06) of Timeshift mount their snapshots to `/run/timeshift/$PID/backup/timeshift-btrfs`. Where `$PID` is the process ID of the currently running Timeshift session. The PID is changing every time Timeshift is opened. grub-btrfsd can automatically take care of the detection of the correct PID and directory if this flag is set. In this case the argument `SNAPSHOTS_DIR` has no effect.
