This bug was fixed in the package init-system-helpers - 1.29ubuntu2 --- init-system-helpers (1.29ubuntu2) xenial; urgency=medium * invoke-rc.d: Under systemd, "runlevel" only switches to 3 or 5 when multi-user.target/graphical.target have been reached, not before. Adjust

The fix seems to work for me. Here's what I did to check: I used a VM (xenial_test) booted from a pristine copy of the image at in a local OpenStack environment to verify the fix. I modified the VM to enable

This commit fixes the bogus "runlevel fails" check: http://anonscm.debian.org/cgit/collab-maint/init-system- helpers.git/commit/?id=2c444f0cd . It does modify behaviour during early boot, but I think this is a correct change; nevertheless I would *not* want to SRU this, as this check has been

[Bug 1575572] Re: apache2 fails to start if installed via cloud config (on Xenial)

I had a closer look how systemd emulates the old runlevels. systemd- update-utmp-runlevel.service runs after graphical.target, multi- user.target etc. started (After=runlevel1.target runlevel2.target runlevel3.target runlevel4.target runlevel5.target, those are activated in multi-user.target

[Bug 1575572] Re: apache2 fails to start if installed via cloud config (on Xenial)

For the record, even after fixing this, installing packages from current cloud-init will still not be 100% reliable in its current form. The design problem here is that cloud-init runs *in* the boot sequence, i. e. in the transaction where default.target and its dependencies get started. You

[Bug 1575572] Re: apache2 fails to start if installed via cloud config (on Xenial)

I tested the output of "runlevel" and the env under Debian sid with sysvinit-core: - In an rcS script: runlevel says "unknown" (env has RUNLEVEL=S and PREVLEVEL=N) - In an rc[2345] script: runlevel says "N 2" (env has RUNLEVEL=2 and PREVLEVEL=N) With systemd, runlevel says "unknown" until

Indeed this isn't related to native systemd units vs. sysvinit scripts. > honor this historical behavior by making the 'runlevel' command return the target runlevel when called from a systemd unit that's run at boot, even if that target has not yet been reached. OK, I wasn't aware of that. I'll

[Bug 1575572] Re: apache2 fails to start if installed via cloud config (on Xenial)

Ok, here is what is happening: a.) dpkg (or apt) install of apache2 (or just about any service) starts services by calling to /usr/sbin/invoke-rc.d (like 'invoke-rc.d apache2 start'). b.) invoke-rc.d calls 'runlevel' to get the current runlevel and see if this service should be started. c.)
