Package: systemd
Version: 241-7~deb10u4
Severity: important

Dear Maintainer,

I'm using libguestfs, which creates a VM images from the packages in my  
debian buster docker.

Very rarely, libguestfs fails detecting one of the LVM volumes it's  
inspecting.

More information on mailing list here:

https://marc.info/?l=libguestfs&m=161762331515987&w=2

The problem is that systemd/udev fails collecting the output of "dmsetup  
splitnames".

This bug was also mentioned here:

https://github.com/systemd/systemd/issues/18190

After I build systemd v248 from source - the problem goes away.

Probably a backport is needed.

Sam
