[Slackbuilds-users] on creating users

The manual method is fine if you build-once / install once.
But if I understood correctly, Miguel's question is about build-once /
install-many, storing the created package centrally and then installing it
on several boxes.
In this case, one might forget to create the user / group on the box where
you're installing it.
I have this same issue and never found a nice & clean solution.
I'm also against automatic user creation and just throwing out a warning
after installation (in doinst.sh) might not be very effective.
As an administrator of several servers and desktops, I use a local solution:
- a shell script wrapper that calls installpkg
- a centralized file with pre- & post- commands to run (pre- like checking
for a user I need, post- like copying some standard configuration files I
use for a specific package)
But this is for local administration and I see no way to implement this in
But, as Robby, I'm open to suggestions to make my life easier :)
