Bugzilla Bug 205293

pkg_config() in the current munin ebuild tries to enter an crontab entry in
this way:

  crontab -u munin /var/lib/munin/crontab

this is correct for the vixie-cron crontab(1)and maybe others, but dcron uses a
slightly different syntax. The correct way to do it with dcron is:

  crontab  /var/lib/munin/crontab -u munin

You could say it's got it backwards, therefore emerge --config
net-analyzer/munin results in the crontab(1) help output and no crontab
installed when dcron is installed.

Not sure if there's already an eclass/function dealing with user cron entries
(cron.eclass doesn't) but extending one would probably be the intelligent fix.

Quicker: drop the automatic installation and simply print instructions on how
to add the crontab for different cron implementations.

Reproducible: Always

Steps to Reproduce:
1. emerge sys-process/dcron
2. emerge net-analyzer/munin
3. emerge --config net-analyzer/munin
Actual Results:  
crontab V3.2
crontab file <opts>  replace crontab from file
crontab -    <opts>  replace crontab from stdin
crontab -u user      specify user
crontab -l [user]    list crontab for user
crontab -e [user]    edit crontab for user
crontab -d [user]    delete crontab for user
crontab -c dir       specify crontab directory


Expected Results:  
crontab should be installed for user munin, or warning given by pkg_config how
to add it manually.

Can I do this safely on dcron?
crontab -u munin </var/lib/munin/crontab

No, but you can do one of those two:
# crontab /var/lib/munin/crontab -u munin
# crontab - -u munin  </var/lib/munin/crontab

I have tried other combinations, which don't work:
# crontab -u munin </var/lib/munin/crontab
# crontab -u munin - </var/lib/munin/crontab
# crontab -u munin /var/lib/munin/crontab

Also, it only works as root:
$ crontab - -u munin </var/lib/munin/crontab
crontab: only the superuser may specify a user

HTH.

> # crontab - -u munin  </var/lib/munin/crontab
That one works on vixie-cron too (the file-specific on does not).


Fixed in 1.3.4 now.
