Tom and I discussed this on IRC, so I'll just throw it in here.
I'd like to make the following changes to our packages:
* Remove initscripts and sysvinit from the base group. * Add systemd-sysvcompat to the base group.
I'd really like to get rid of the /bin/systemd symlink if we're going to do this. I suppose it can just be part of the news item we post.
Why did you even introduce this symlink in the first place? Why did you not remove this symlink _before_ we told everyone to use init=/bin/systemd on their command line? If you knew this symlink was going to disappear eventually, why not tell everyone to use init=/usr/lib/systemd/systemd from the beginning? (Not trying to be rude, I really need a history lesson on this.)
As not all packages are equipped with systemd units yet, a compatibility layer exists: You can install the initscripts package, which does not depend on sysvinit any longer (and thus doesn't conflict with systemd-syscompat). A new initscripts installation will come with an empty DAEMONS array by default. Once you add rc.d scripts to DAEMONS, systemd will generate compatibility units for those services, or enable the systemd unit if a unit with the same name exists.
This "compatability" layer is still a mess with packages shipping rc.d files which don't match up with the unit file name. I proposed a solution for this in initscripts that involved keeping a static list of exceptions in arch-daemons rather than peppering packages with symlinks full of lies, and it appears that nothing has been done yet. This _must_ to be fixed first.
In the current status, only a small number of people will even need it, and they will only specify services which do not have a unit at all - and nothing is broken there. I don't really see the problem - can't we expect our users to gradually remove the compatibility DAEMONS over time? Do we really have to hold their hands? Can you give a link to your proposed patches? I am really not against improving this, I just don't see it as a showstopper.
