Package: systemd
Version: 250.3-1
Severity: normal
File: /usr/bin/systemctl
Dear Maintainer,
According to the systemctl.1 man page, it should be possible to specify
`--wait` to systemctl commands that will start units, to have the
systemctl command block until the units terminate again. This seems to
work as expected for system units, but not for user units.
The attached short script provides a simple test case: given appropriate
ssh configuration, when run with `sudo bash test.sh` it will create a
new user called "test" with a simple example service template unit, then
log in through using ssh to start that unit twice, once without
`--wait`, and once with. Expected behaviour is for this script to
start both unit instances, with the second one sleeping before the
script finishes. Actual behaviour is that the first unit starts as
expected, but the second unit is never started, and the attempt gives a
return code of 1 and the following error printed to the terminal:
Failed to connect to bus: No such file or directory
As I say, the `--wait` function works as expected for system units; it's
only with user units that it seems to fail.
Kind regards,
Adam
