Subject: [gentoo-alt] [PREFIX] Prefix rsync now includes full gentoo-x86 repo

1 All,

3 This is a headsup mostly for developers. The (good) news for users is
4 that all packages from regular Gentoo are now also available for Prefix
5 albeit being masked by missing keywords.
6
7 Because of a growing whitelist.txt, and the tiresome process of adding
8 to whitelist.txt what is necessary, then waiting around an hour to sync
9 and find the next missing package, I decided to include all packages
10 from gx86 in the Prefix rsync tree.
11
12 Of course "each advantage has its disadvantage", to quote Cruyff. In
13 the attached figure, the most prominent disadvantage is made visual:
14 generation time has increased from ~12 to ~17 minutes. For the 30
15 minutes rotation this obviously makes no difference.
16
17 Notice the bump of time necessary by egencache around 20:00, that is the
18 time Zac committed "cache-formats = md5-dict pms" to
19 metadata/layout.conf. In the Prefix tree, there now is a
20 metadata/md5-cache directory that should ultimately fix the bug we
21 observed in the past [1], but gentoo-x86 people have been affected by
22 now too [2]. That sort of is a proof that I was correctly not
23 convinced in comment #17 of said Prefix bug [1].
24
25 In the near future, we (Prefix) might jump ahead and stop distributing
26 the old metadata/cache, but for now we have both, like gx86.
27
28 Because the Prefix overlay now "overshadows" the gx86 tree, I've removed
29 whitelist.txt, since it's obviously no longer used. Nothing is
30 necessary any more to "include" something in Prefix, as everything there
31 is, should be there now.
