replace-systemd: example boots but systemctl can't find shared library.

[jmarrero]

systemctl: error while loading shared libraries: libsystemd-shared-251.7-611.fc37.so: cannot open shared object file: No such file or directory

I updated the example because it was no longer building but to build I needed to remove /var/libs

/var/libs content I imagine was important?

[jmarrero]

Any quick and fast way to resolve this or remove the example for now?

[jmarrero]

No luck with an upgrade using: https://bodhi.fedoraproject.org/updates/FEDORA-2022-a82842a059 either:

What seems to be happening is that for some reason the /usr/bin/systemctl is left at the old version. Doing rpm --reinstall https://kojipkgs.fedoraproject.org//packages/systemd/251.6/609.fc37/x86_64/systemd-251.6-609.fc37.x86_64.rpm fixes it here.

# rpm -V systemd|grep -Fv '.......T.' | grep -v missing
....L....    /usr/lib/systemd/system/default.target
# rpm-ostree override replace https://bodhi.fedoraproject.org/updates/FEDORA-2022-bb55f82158
...
(apparent success)
...
# sha256sum /usr/bin/systemctl
acac0aa21c430381bf7e4bcb48f1e85d8d1cd0530b6ee682e1d47cee725aefd4  /usr/bin/systemctl
# rpm -V systemd|grep -Fv '.......T.' | grep -v missing
..5....T.    /usr/bin/systemctl
# 

So it's just somehow only that binary...

[cgwalters]

Oh man, of course...the problem is our cliwrap logic again...we're swapping it back to the old binary. To handle this, I think we may need to detect the case where /usr/bin/systemctl got swapped back, and then just delete the old version.

[jmarrero]

thanks for the workaround here is in a PR: #50
Lets leave this issue open while we get a proper fix in rpm-ostree to remove the workaround then.
