This looks like something that a lower level X ebuild should be installing. The problem here is that there's also a bit of funny business going on when portage encounters a merge of some filetype being blocked by a different filetype. In the above case, if some X11 package installs the /usr/lib/X11/app-defaults symlink and all other apps install to /etc/X11/app-defaults then everything should be fine. > * "/usr/share/cups/model/foomatic-ppds -> /usr/share/ppd" is > installed by both net-print/foomatic-db and net-print/hplip. Again, given the name of the symlink, net-print/hplip should probably be installing directly to /usr/share/ppd. > Maybe this particular packages could be hacked to avoid need for > the symlinks (or the symlinks should be installed only by some > lower level, depended-on, packages?), but anyway it would be hard > to do a strict sanity check of the whole tree.

Yep, it seems that changing the behaviour will lead to some breakage. However repoman is definately not capable of handling this sort of stuff. Also, none of the breakage (that you've revealed here at least) is that bad. Putting the relevant collision-protect changes into ~arch and following up with the actual unmerge changes should lead to minimal disruption on the user's side. -- Jason Stubbs -- gentoo-dev@gentoo.org mailing list
