systemd (229-4ubuntu21.22) xenial; urgency=medium
[ Dan Streetman ]
* d/t/systemd-fsckd, d/t/cmdline-upstart-boot:
- skip on s390x; requires grub (LP: #1830477)
* d/p/ask-password-prevent-buffer-overrow-when-reading-fro.patch:
- prevent buffer overflow when reading keyring (LP: #1814373)
[ Dimitri John Ledkov ]
* Specify Ubuntu's Vcs-Git
[ Balint Reczey ]
* Append /snap/bin to default PATH.
Snapd ships snapd-env-generator, but systemd does not not support
environment generators. Hard-coding /snap/bin is less risky than
backporting environment generator support and since snaps are considered
to be first class packages on Ubuntu /snap/bin can safely added to
the default PATH. (LP: #1771858)
[ Ioanna Alifieraki ]
* d/p/systemctl-Replace-check_one_unit-by-get_state_one_un.patch
- Backport upstream PR#2768 needed for next patch
* d/p/systemctl-load-unit-if-needed-in-systemctl-is-active.patch
- Backport upstream PR#7997 to fix alias service reports inactive while
aliased is active (LP: #1828892)

Title:
systemctl - alias service reports inactive while aliased is active
Status in systemd package in Ubuntu:
Fix Released
Status in systemd source package in Xenial:
Fix Released
Bug description:
[Impact]
'systemctl is-active' command reports an alias service as inactive even
though the aliased service
is active.
Currently the 'systemctl is-active' command does not load units to minimise
its effect on the system (i.e. that a monitoring command does not itself alter
the state of the system).
However, this behaviour leads to inconsistencies when services are aliased.
[Test case]
- Test case 1 - libvirtd
alias service : libvirtd
aliased service : libvirt-bin
/etc/systemd/system$ ls -la libvirtd.service
lrwxrwxrwx 1 root root 39 May 13 20:49 libvirtd.service ->
/lib/systemd/system/libvirt-bin.service
$ systemctl is-active libvirtd
inactive
$ systemctl is-active libvirt-bin
active
- Test case 2 - sshd
alias service : sshd
aliased service : ssh
/ect/systemd/system$ ls -la sshd.service
lrwxrwxrwx 1 root root 31 Mar 19 19:44 sshd.service ->
/lib/systemd/system/ssh.service
$ systemctl is-active sshd
inactive
$ systemctl is-active ssh
active
[Regression Potential]
This fix may result into systemctl reporting inconsistent information
concerning the status of a service.
