Nut upsdev - Apr 2012 - Fix broken systemd integration in the build system

Hi Michal,

I'm finally back on systemd integration with NUT.
I've cc'ed Stanislav, since I've heard Suse is moving to systemd
too.

I've been investigation on your systemd integration in the tree, found a
strange integration and understood why.
I've fixed this with 2 commits:
- r3528: only generate .in from configure, thus removing this annoying
autoreconf msg
- r3529: which you will want to revert for now, since it removes the
hardcoded paths... see below.

so all this lead my again to an incomplete effort on my side: the NUT
Packaging Standard.
here, upsd and upsmon are installed in /usr/bin, while upsdrvctl and
drivers are in /sbin.
thus you can't use configure pattern substitution (@SBINDIR@) to remove
hard coded paths in template files.

so for now, once 2.6.4 is out, just revert r3529.
I'll then relaunch this NPS effort, for 2.8 series, and we'll have rooms
to
discuss all these packaging things.

on a separate topic, we will also (Stan, you and I) have to discuss systemd
and halt hook.
You (Michal) may want to revive the thread you told me, including -upsdev
list this time.
I'll moderate cross msg on the nut side...

cheers,
Arnaud

This is no longer true for Fedora. Since Fedora 17, there is no /bin nor 
/sbin now. Everything got moved to /usr/(s)bin. They are symlinks to 
/usr... for now.

Don't ask me why they did it, I don't know it either.
They tried to explain it in
http://www.freedesktop.org/wiki/Software/systemd/TheCaseForTheUsrMerge
http://www.freedesktop.org/wiki/Software/systemd/separate-usr-is-broken
but I'm not convinced.

what do you mean exactly?

My memory is failing, I don't know what thread you mean?

Long ago, Nostradamus foresaw that on Apr 11, Michal Hlavinka would write:

In the /sbin world, I have been creating custom nut packages that put
all the drivers in /sbin/ups.  This reduces changes of name conflicts
on a driver, and has less clutter.  Other packages use /usr/libexec for
plugins and drivers.
