Removing runlevel 06 no longer needed?

[Bryan Quigley]

Hi all,

I've been looking at merging keepalived or snmpd with Debian and they
both have something like:
explicit init start/stop parameters (don't stop at 0 and 6)
Call dh_installinit correctly to avoid installing links in rc[06].d

As far as I can tell that was an Upstart specific workaround[1].  Am I
correct in that?  Can those differences be dropped now that we are on
systemd?

Thanks,
Bryan
