Re: [gentoo-dev] [PATCH] gnome2-utils.eclass add support for gdk-pixbuf cache update

[Gilles Dartiguelongue <eva@gentoo.org>]

One last point to handle, how to migrate gdk-pixbuf.cache so that it is
owned by the ebuild ?

I've discussed this with Michał and it seems two options are possible.

1. rm the file on the filesystem in pkg_preinst in gdk-pixbuf ebuild
pros:
  - works immediately without fiddling with profiles (see 2)
cons:
  - no idea what PMS says about it, Michał told me it shouldn't work yet
my testing proves otherwise.
  - leaves the system with no loaders.cache for a while which could
result in apps starting with no lots of missing icons.

2. use COLLISION_IGNORE in profiles/base/make.conf
pros:
  - does not leave the system without the cache file
cons:
  - add a setting to base/make.conf for a long period of time to ensure
most of our user have migrated (how long would it be btw, 6 months, 1
year ?)
  - does not protect other packages from owning the package due to this
very solution for the time the setting is left in base/make.conf

3. write a news item and let users handle it


Is there any other solution or is there any other point that would move
the balance from one solution to another ?

This solution would also be applied to a couple of other commonly
regenerated files in Gnome ebuilds, like gtk-icon-cache, etc.
