Bugzilla Bug 97589

When using mailwrapper flag posfix and sendmail still have conflicting files
which are detected by collision-protect portage feature. Discussion about this
has been going on at bug #97268. I'm opening a new one for the sake of clarity.

These are the affected files:

existing file /usr/bin/rmail is not owned by this package
existing file /usr/share/man/man1/newaliases.1.gz is not owned by this package
existing file /usr/share/man/man1/mailq.1.gz is not owned by this package
existing file /usr/share/man/man5/aliases.5.gz is not owned by this package


Reproducible: Always
Steps to Reproduce:
1. USE="mailwrapper" emerge sendmail
2. USE="mailwrapper" emerge postfix
3.

I've just talked to slarti about this, and we decided to have manpages
installed
as f.e. mailq-postfix.1.gz, mailq-sendmail.1.gz, and let mailq.1.gz be a
symlink
to the correct manpage. The symlink would be controlled by mailer-config (or
mailer eselect module).

This way, abovementioned collision is solved, user always gets correct manpage,
and as an added bonus, manpages for any installed MTA are available via f.e.
`man newaliases-sendmail`.

I'm hopefully going to have a look at this during the weekend.

Any suggestions/improvements?

mailer-config-0.2 implements manpages handling, as suggested above. Handled
manpages currently are:

sendmail.1    - postfix, esmtp
sendmail.8    - sendmail
newaliases.1  - postfix, esmtp, sendmail
mailq.1       - postfix, esmtp, sendmail
aliases.5     - postfix, sendmail

By saying f.e. `man newaliases`, you will get manpage belonging to currently
selected profile/MTA, or "No manual entry for ...", if that MTA doesn't provide
such manpage.

As for other MTAs:
I have the mailer-config-aware ebuild ready (bug #97657), I'm waiting for exim
maintainers' opinion. Exim only installs one manpage - exim.1
I'll have a look at the rest sometime soon.

Looks like /usr/bin/rmail also needs to be handled, as it is provided by
postfix, sendmail and exim (so far I've figured).

/usr/bin/rmail is also provided by courier, as well as rmail.1 manpage

Can somebody put some updates on this. It has been one year and some pointers
to where to start to help would be cool.
