The problem occurs on Fedora 38/39 and Rocky 9, NOT on Rocky 8. Due to
CGroup differences.

Hi,
HTCondor 23.4 breaks 'condor_submit -i' too on current Fedora.
Debugging this a bit further, leads to suspecting, that the changes in
proc_family_direct_cgroup_v2.cpp
around 23.2 seem to get confused in the hierarchy of CGroups,
and mixing e.g.:
/sys/fs/cgroup/htcondor/condor_usr_data_condor_execute_slot1_1@xxxxxxxxxxxxxxxxxxxxxx
and
/sys/fs/cgroup/htcondor/condor_usr_data_condor_execute_slot1_1@xxxxxxxxxxxxxxxxxxxxxx/sshd
Actually, it's not clear to me why the second even exists, but CGroups
is not my daily drink, at all...
Workaround is still to revert (part of) proc_family_direct_cgroup_v2.cpp
Regards, B.
