Missing grub-btrfsd daemon

[Guthauser]

I've got an running version of grub-btrfs and it works so far. Now i wanted to Automatically update grub upon snapshot creation or deletion. If I want to do so with

sudo systemctl start grub-btrfsd

I get following output:

Failed to start grub-btrfsd.service: Unit grub-btrfsd.service not found.

Did I miss a something to install?

Probably yes, can you give some more info about how you installed grub-btrfs and what distro you are using? Maybe also the content of /usr/lib/systemd/system?

Im using ParrotOS 6.0 and installed grub-btrfs via command

sudo apt install grub-btrfs

Didn't do anything other than that configuration/installation wise. (As far as I remember)

Content of /usr/lib/systemd/system:

Also I can't recover snapshots listed in grub. I'll open another issue for that, but thought it's worth mentioning here because its maybe related?

It seems like parrot OS is having an older version of grub-btrfs in their repository. This looks like 4.11, although I am not sure. So maybe refer to the README of this version on how to activate the service (https://github.com/Antynea/grub-btrfs/tree/79ae25ea5d35a9252ab399aee569d70c3a9f1ee2) or upgrade.
