This patch changes the way user managers set the default umask for the units it manages. Indeed one can expect that if user manager's umask is redefined through PAM (via /etc/login.defs or pam_umask), all its children including the units it spawns have their umask set to the new value. Hence make user units inherit their umask value from their parent instead of the hard coded value 0022 but allow them to override this value via their unit file. Note that reexecuting managers with 'systemctl daemon-reexec' after changing UMask= has no effect. To take effect managers need to be restarted with 'systemct restart' instead. This behavior was already present before this patch. Fixes #6077.
