Comment 8 for bug 1931104

After some work and testing, here are my findings.

 - The dogtag-pki autopkgtest failure is manually reproducible
   using autopkgtest-virt-lxd.
 - The dogtag-pki autopkgtests pass with in Impish using
   libnss3 *from the archive* (uploaded and built on Hirsute).
 - The dogtag-pki autopkgtests FAIL when using the very same
   libnss3 version but rebuilt from source on a Hirsute schroot.
   The debdiff between the two binary packages is:

File lists identical (after any substitutions)

Control files: lines which differ (wdiff format)
------------------------------------------------
Installed-Size: [-4255-] {+4318+}

 - This seems to be s390x-specific (I can't reproduce on my
   amd64 laptop)
 - I tried merging the latest version of src:nss from Debian,
   which required refreshing a s390x-specific patch, so I was
   really hoping this would fix it, but no: it fails in the
   same way.

FWIW I have a branch ready for merging 2:3.67-2 to Impish, but
I'm not sure on how to handle this dogtag-pki autopkgtest failure.
