I spoke with Jeffrey Hutzelman about this, trying to sort it out because it still occurs. He calls it a packaging bug and says heimdal's version (if installed) should always over-ride the version supplied by openafs since heimdal's provides more funtionality. Here's his reponse pasted: Ah, OK. I'd call that a packaging bug. What pagsh does is give you a shell in a new PAG, so it can have different AFS tokens than the parent. Essentially, pagsh is to AFS tokens what newgrp is to UNIX groups. It's a basic tool so it comes with AFS, and should be part of the same package that contains other AFS client tools. However, if heimdal is installed, you want its version of pagsh, because it has additional functionality. Particularly, the heimdal version also gives the subshell new Kerberos ticket caches, so in addition to having distinct tokens from the parent, it also has distinct tickets. Most packaging systems have a redirect or override feature designed to deal with this kind of situation. Typically, the heimdal package would be changed such that its version of pagsh overrides the openafs one, but only when both packages are installed. -- Jeff
how about changing the pagsh install-path for both openafs and heimdal and introduce yet another eselect module to let the user choose?
(In reply to comment #2) > how about changing the pagsh install-path for both openafs and heimdal and > introduce yet another eselect module to let the user choose? Isn't eselect a bit overkill for this situation? Also, there's nothing much to choose, because you want the heimdal implementation whenever heimdal is installed, otherwise you want the openafs implementation. Choise would only add confusion here.
This version is no longer in portage. Versions in portage do not produce the same package collisions.
