Use service module for rootless systemd

[xoxys]

Hi, is there a way to use the service module with systemd services running on a non-privileged user? Just using sudo doesn't seems to work:

    with host.sudo(user="renovate"):
        service = host.service("renovate.timer")
        assert service.is_enabled

cls = <class 'abc.SystemdService'>
args = ('find -L /etc/rc?.d/ -name %s', 'S??renovate.timer'), kwargs = {}

    @classmethod
    def check_output(cls, *args, **kwargs):
>       return cls._host.check_output(*args, **kwargs)
E       AssertionError: Unexpected exit code 1 for CommandResult(command=b'sudo -u renovate /bin/sh -c \'find -L /etc/rc?.d/ -name \'"\'"\'S??renovate.timer\'"\'"\'\'', exit_status=1, stdout=None, stderr=b'find: Failed to restore initial working directory: /root: Permission denied\n')
E       assert 1 == 0
E        +  where 1 = CommandResult(command=b'sudo -u renovate /bin/sh -c \'find -L /etc/rc?.d/ -name \'"\'"\'S??renovate.timer\'"\'"\'\'', exit_status=1, stdout=None, stderr=b'find: Failed to restore initial working directory: /root: Permission denied\n').rc

Not sure what's going on here, but you're looking for a systemd thing (ie. a timer), but the code looks like it's using the SysV code to do a 'find'. The systemd is_enabled method (https://github.com/pytest-dev/pytest-testinfra/blob/main/testinfra/modules/service.py#L152) uses systemctl which should work fine with sudo.

Yeah, that's weird, but I have no idea why the SysV code is used.

The SysV code is a fallback:

pytest-testinfra/testinfra/modules/service.py

Lines 153 to 162 in 8d69308

	@property
	def is_enabled(self):
	cmd = self.run_test("systemctl is-enabled %s", self.name)
	if cmd.rc == 0:
	return True
	if cmd.stdout.strip() == "disabled":
	return False
	# Fallback on SysV
	# https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=760616
	return super().is_enabled

I get a similar error when I try to check a non-existing service as user root:

with host.sudo():
    srv = ansiblehost.service("nonexisting.service")
    assert srv.is_enabled
    assert srv.is_running

cls = <class 'testinfra.modules.base.SystemdService'>, args = ('find -L /etc/rc?.d/ -name %s', 'S??nonexisting.service'), kwargs = {}

    @classmethod
    def check_output(cls, *args, **kwargs):
>       return cls._host.check_output(*args, **kwargs)
E       AssertionError: Unexpected exit code 1 for CommandResult(command=b"find -L /etc/rc?.d/ -name 'S??nonexisting.service'", exit_status=1, stdout=None, stderr=b'find: \xe2\x80\x98/etc/rc?.d/\xe2\x80\x99: No such file or directory\n')
E       assert 1 == 0
E        +  where 1 = CommandResult(command=b"find -L /etc/rc?.d/ -name 'S??nonexisting.service'", exit_status=1, stdout=None, stderr=b'find: \xe2\x80\x98/etc/rc?.d/\xe2\x80\x99: No such file or directory\n').rc

Since I use "root", I do not get the permission error that was mentioned initially
