Dear Maintainers,
We can confirm that this bug affects all pv and pvh domUs that use pvgrub.
The commit responsible is 20239c28 "Bump debhelper from old 10 to 13." [1]
The relevant change in debhelper came with version v11: "The dh_strip
and dh_shlibdeps tools no longer uses filename patterns to determine
which files to process. Instead, they open the file and look for an ELF
header to determine if a given file is an shared object or an ELF
executable."
By choosing debhelper 13, this led to pv grub getting stripped.
A simple override to dh_strip mitigates the issue.
We assume that testing and unstable are affected as well but we do not
have systems to test this.
Cheers,
Valentin
