Full Text Bug Listing

I emerged courier and courier-imap, when I wanted to start courier
(/etc/init.d/courier 
start) it complained about a missing "/var/lib/courier/authdaemon/lock" because
the 
"authdaemon" dir was created in "courier-imap" instead of "courier". 

Either courier-imap doesn't use its own /var/lib/ dir OR courier itself has its 
authdaemon dir set to courier-imap [which is more or less not logical] 

I haven't looked into courier in detail, but I think haveing two /etc dirs is
not the best, 
as I see there are several double files (pop config in courier and
courier-imap) which 
might be confusing to config. 

Reproducible: Always
Steps to Reproduce:
1. emerge courier courier-imap 
2. /etc/init.d/courier start 
3. 
Actual Results:  
courier fails to start because /var/lib/courier/authdaemon/lock file can't be
created (dir 
does not exist) 

Expected Results:  
courier started 

perhaps merge /etc/courier and /etc/courier-imap and /var/lib/courier and 
/var/lib/courier-imap

courier and courier-imap should not be installed at the same time.  courier
contains courier-imap already.

then, for gods sake, Block each other package. it should be possible to either
block courier-imap from installing when courier is installed, or vica versa. if
this is not possible, then this is either A) a very important feature for
portage, or B) (more logical) imap functionallty has to be turned of in courier
so courier and courier-imap are two seperate packages that complement each
other.

If you read the courier webpage you will notice that courier can be installed
in 
separate parts. There are reasons for this. Sometimes courier-imap is used with
other 
mta's. Maildrop (part of courier) can be installed to take the place of
procmail. Or 
you can get the whole shebang with courier. Some people might want to install 
courier-imap and courier at the same time (i.e. for converting from
courier-imap/
some-other-mta -> courier with only one box). While I do think we should
attempt to 
make some things difficult to do, so inexperienced sys-admins don't shoot off
their 
own toes, this is not one of them. 

if I download the source from the courier webpage and do it myself I can shoot 
myself int he foot. but if a linux distribution gives me two packages called courier 
and courier-imap, I first think (and I am sure I am not the only one), that courier is 
pop/smtp without imap and courier-imap is the imap adon. 
it is not so, good, then why don't you block each other package? shoudln't be too 
complicated. 

i vote having courier installed should block the standalone
courier-imap/maildrop/etc and vice-versa.

Maybe instead of blocking via DEPEND, through a function in pkg_setup which
dies if it detects a conflicting Mr. Sam package already installed and
informing the user of the problem and valid choices for a solution?  Just a
thought.  What do you think iggy?

I still think it's a bad idea to just block something like that. I've
personally had to move from 
qmail/courier-imap -> courier back in my Slackware days, and if I had been
unable to install both 
on the same system, I would have been SOL. I can do a conditional warning that
says something 
along the lines of "you already have courier-imap installed, courier includes
this functionality, so 
you should remove it unless you need it". Would that satisfy everybody? Maybe
we could talk 
robbat2 into doing something similar. 

Iggy: doing that would break non-interactive emerges. Eg user does emerge -p
... and it all shows fine, then leave emerge ... running and comes back in the
morning to find the second item, courier, stopped his entire list to emerges.

I'm strongly with Nick on this one. A precedent for doing this already exists
with MTAs anyway. 
try:
emerge -p qmail sendmail

Fine, done. 
added !virtual/imapd to RDEPEND 

the problem here isn't that courier-imap and courier get installed
concurrently, but courier-imap's initscript not working if ONLY the
courier-imapd is installed

it just erroneously looks into /usr/lib/courier which simply doesn't exist
(unless you install the courier package)

moved the version that fixes this to x86
