Hi All,

I have issues with the shell completion of the systemctl 'start' command: it 
does not take disabled units into account.

I've been trying to solve this issue in a zsh completion function of mine. 
Since there is no straight-forward way to get all inactive units including 
disabled ones (2), I tried with 'list-unit-files':

  _some_units_files=( $(systemctl --full --no-legend --no-pager list-unit-files | 
cut -d' ' -f1 | grep -E '[^@]\.*\.(device|snapshot)$' 2>/dev/null ) );
  systemctl show --property "$property" -- $_some_units_files

which produces multiple: "Failed to issue method call: Unknown unit" (1)
BTW, I'm not sure about removing unit files containing '@' ("Unit name 
[email protected] is not valid")...

Trying to narrow down:

  for u in $_some_units_files ; do echo "=== $u ==="; systemctl show --no-pager --property 
"CanStart" -- "$u" ; done

...
=== udev-configure-printer.service ===
Failed to issue method call: Unknown unit
zsh: exit 1     systemctl show --no-pager --property "CanStart" -- "$u"
...

But

  systemctl show --property "CanStart" -- udev-configure-printer.service
CanStart=yes

?

kind regards
Foudil

(1) seems related to: dbus_set_error_const(&e, DBUS_ERROR_UNKNOWN_OBJECT, "Unknown 
unit");
