[gentoo-dev] How to force homedir on enewuser

Hi,

Following situation: Older mailman ebuilds used to set the mailman user home 
to /usr/local/mailman (which is obviously wrong).

Now with the new mailman ebuild, various directories are configurable.

The mailman user is created with the enewuser macro. Now, the problem is that 
enewuser just exits with zero if the user already exists. Thus the old 
homedir is kept.

What is the correct way to handle this? I'd suggest that enewuser might get 
some "force"-parameter that tells it to delete and recreate the user if it 
already exists. Thoughts?

(If noone comes around with a better idea, I'll open a bug with a feature 
request within a few days)

Tell the user to do it manually in pkg_setup/postinst. This is
something that IMO shouldn't be done by the ebuild/package manager for
two reasons:
- extreme cornercase, or how often does this come up?
- the system might rely on the current settings in unexpected ways

right, there is no way (by design) to force these settings on an already 
created user.  if the old path really truly should not be the old value, you 
can do something like this in pkg_setup:
if [[ $(egetent passwd user | cut -d: -f6) == "/the/old/path" ]] ; then
	eerror "please run usermod -m -d /new/path ......"
	die "moocow"
fi

You should also ensure that ${ROOT} is /
