Not sure if the documentation is out of date or something else but the README.Debian suggests this which fails:

$ sudo systemctl enable btrfsmaintenance-refresh.watch
Failed to enable unit: Unit btrfsmaintenance-refresh.watch.service does not exist

Hello Eric,

I'm not sure where you've found that command, but it's not README.Debian
in btrfsmaintenance_0.5.2-1 :

grep 'sudo systemctl enable btrfsmaintenance-refresh.watch' \
     /usr/share/doc/btrfsmaintenance/README.Debian \
     || echo "NOT FOUND"

There have been a bunch of clarity fixes since 0.5.2-1 that haven't been
uploaded yet.  Here's how to access them:

git clone https://salsa.debian.org/sten/btrfsmaintenance.git

or you can try this prebuilt prerelease:

https://people.debian.org/~sten/test-builds/btrfsmaintenance_0.5.2-2_all.deb
  (you can use the changes file signature and checksums to verify)
https://people.debian.org/~sten/test-builds/

Given this:

I'm guessing you're not interested in thinking about if any
documentation fixes should be attempted to be made in stable-updates?

Best,
Nicholas
