[Bug 1448656] Re: systemd doesn't allow proper shutdown after it encountered errornous .service

[Martin Pitt]

"systemctl status foo.service" ought to have an error message that the
unit file is broken. However, comments in ExecStart= are just passed on
verbatim to whatever you execute, so this should reflect in some
specific error message? I. e. if I have

$ cat /etc/systemd/system/broken.service 
[Service]
ExecStart=/bin/sleep 1 # muhaha

$ sudo systemctl daemon-reload
$ sudo systemctl start broken.service
$ systemctl status broken.service
● broken.service
   Loaded: loaded (/etc/systemd/system/broken.service; static; vendor preset: enabled)
   Active: failed (Result: exit-code) since Di 2015-06-02 12:39:05 CEST; 7s ago
  Process: 12139 ExecStart=/bin/sleep 1 # muhaha (code=exited, status=1/FAILURE)
 Main PID: 12139 (code=exited, status=1/FAILURE)

Jun 02 12:39:05 donald systemd[1]: Unit broken.service entered failed state.
Jun 02 12:39:05 donald systemd[1]: broken.service failed.

which seems quite clear? (Sorry for the German error messages, they
basically say "invalid time interval")

Title:
  systemd doesn't allow proper shutdown after it encountered errornous
  .service

Status in systemd package in Ubuntu:
  Invalid

Bug description:
  Assume you have created a `.service` unit file in
  `/lib/systemd/system/` with a syntax error and reboot. At system start
  the start of the unit fails, but then the system/`systemd` no longer
  responds to <kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>Del</kbd> and the
  system needs to be killed by pulling the plug. That can corrupt the
  system because services which on shutdown hook, like a write-back
  cache which needs to write data back to disks before the machine is
  turned of, aren't executed.

  It'd be better if the errornous service/unit would be skipped, a
  rescue shell provided or at least a possibility to shutdown properly
  given.
