There was a problem hiding this comment.
can we add a line here
# set PYTHONPATH, so the build system doesn't silently skip installing `ceph-volume`
?

@srhb @flokli Why was this needed?
Isn't this what
pythonPath = [ ceph-python-env "${placeholder "out"}/${ceph-python-env.sitePackages}" ];
does? (I haven't found yet where exactly the usage of pythonPath in mkDerivation is implemented)
I found it confusing that we currently set both, so it would be nice to understand why pythonPath isn't enough.

Motivation for this change
In #73187 ceph-volume unfortunately got lost. I completely missed this in the backport as well, which means that OSDs using bluestore become inoperable. Therefore, this needs a backport asap.
Things done
Brought back the (admittedly hacky) pythonpath shenanigans that enable the build system to pick up the necessities and not silently skip installing ceph-volume and friends.
Deployed to a testing cluster and noted that ceph-volume correctly activates bluestore volumes. It seems the python wrapper is no longer necessary, the path is baked into the .py file.
