Emil,
Ken and I talked about this, I think the right thing to do is something like:
sysdir = get_option('sysconfdir')
if not sysdir.startswith('/')
sysdir = join_paths(get_option('prefix'), sysdir)
endif
So that if someone sets --sysconfdir=/etc and --prefix=/usr they get what they
want (libs in /usr/lib and drirc in /etc), but if say a BSD sets --syconfdir=etc
--prefux=/usr/local they get what they (libs in /usr/local/libs and drirc in
/usr/local/etc)
Does that seem right to you?
