Title: #886: sudo: get timezone information from previous value when
constructing new usn
alexey-tikhonov commented:
"""
It is weird but `make intgcheck-run` hangs with this patch everywhere (local
macine, internal CI, GH CI)
When hang there are several sssd processes running. Looks like monitor is
awaiting children to finish, sssd_nss is awaiting be[LDAP] and be[LDAP] is
awaiting monitor...
Probably patch is not direct cause of the problem.
