Application unconfigurable due to file "/etc/sysconfig/btrfsmaintenance" does not exist after installing on ubuntu 20.04

The following message is self-explanatory:

Description: automate btrfs maintenance tasks on mountpoints or directories
 This is a set of scripts for the btrfs filesystem that automates the
 following maintenance tasks: scrub, balance, trim, and defragment.
 .
 Tasks are enabled, disabled, scheduled, and customised from a single
 text file.  The default configuration assumes an installation profile
 where / is a btrfs filesystem.
 .
 The default values have been chosen as an even compromise between
 time to complete maintenance, improvement in filesystem performance,
 and minimum impact on other processes.  Please note that I/O priority
 scheduling requires the use of CFQ, and not noop, deadline,
 anticipatory, or blk-mq.  CFQ is Debian's default block scheduler.

xxx@pop-os:~$ cat /etc/sysconfig/btrfsmaintenance
cat: /etc/sysconfig/btrfsmaintenance: No such file or directory

How could this happen? If this important file is missing in the repo it will be useless

According to documentation in /usr/share/docs/btrfsmaintenance/README.Debian, the configuration is expected in /etc/default/btrfsmaintenance which is available, as far as I can see. At least with 0.5-1, which is being used in Ubuntu and in Debian unstable. Sorry, don't have a stable version of Debian at hand. But in the worst case this probably is just an error in the old version of the package?!

Thanks Lot. Will check immediately

Hi,

Yes, this was my fault (I missed this docstring, and no one noticed until June 2021). The fix is in git still hasn't been uploaded, but is essentially just:

--- a/btrfsmaintenance-refresh.service +++ b/btrfsmaintenance-refresh.service @@ -1,5 +1,6 @@ [Unit]

• Description=Update cron periods from /etc/sysconfig/btrfsmaintenance
• Description=Update cron periods from /etc/default/btrfsmaintenance

• Documentation="file:/usr/share/doc/btrfsmaintenance/README.md.gz"

  [Service]

I'm still investigating a better way to set add/enhance the Documentation key, because systemd doesn't support either markdown files or compressed markdown files. I contacted systemd upstream, and they want man pages to be used for this value, and I chose to delay uploading 0.5-2.

thanks a lot, it is indeed there!

Does this only affect document or other files?

What are you referring to when you write "this"? /etc/default/btrfsmaintenance?

[tribbloid]

@sten0 Sorry I just saw /etc/default/btrfsmaintenance in the readme file. So it should be a false alarm.

The btrfsmaintenance-refresh.service fix is nice to have, but eventually the readme file should give enough information
