Request for Discussion about Account Handling in Maintainer Scripts Wiki Page
|
|
| Marc Haber 2006-09-29, 1:53 pm |
| Hi,
Whether an account created by a package should be deleted or not has
been discussed a million times. But it looks like the results of these
discussions were never written down.
I have created a wiki page,
http://wiki.debian.org/AccountHandl...intainerScripts
which tries to neutrally summarize my knowledge about what to do with
system accounts needed by packages.
Of course, a big part of the debate is whether to remove accounts in
postinst or not, and whether to do it during removal or during purge.
This is the actually most important part of discussion IMO since I
think it should be avoided to add complexity to maintainer scripts.
I'd like to solicit your opinions to this wiki page and would
appreciate if we could have the discussion here and have me
incorporate the changes into the wiki page. That way, rationales can
be put into the wiki text as well.
Greetings
Marc

The removal of users / groups is not the only thing often debated for
purges. I propose to enlarge the debate on purging to:
- log files
- databases
- caches
- other perhaps valuable data
Perhaps thoughts on these subjects are connected (I for example think
that we should let the admin decide, perhaps in /etc/dpkg/purges.conf,
what he wants to delete on purges) and should be grouped in
implementation and/or policy updates?
.. o O ( It's funny, I discussed this no later than yesterday on a Debianish
channel again. )

It looks like a pretty good summary to me, I don't think I have anything to
add.
Cheers,

I fully agree here. Best would be a central package (dpkg-custom for
example) to configure purge behaviour for accounts, log files, DBs etc.
One way would be a shell sourcefile providing functions like del_user(),
purge_logs(), purge_cache() etc.
The biggest problem still would be, that one cannot rely on it still being
available at purge time. So the only clean way to implement this, is to
implement it directly in dpkg.
