[gentoo-dev] RFC: Remove .lzma in favor of .xz portage snapshots

[Jeremy Olexa]

 Hello all, This email is to solicit concerns or thoughts about removing 
 the .lzma portage snapshots.

 The facts:
 - Starting on 2011-03-03, I enabled .xz compression on snapshots that 
 Gentoo makes available[1].
 - On 2011-01-05, Mike added[2] .xz support to emerge-webrsync.
 - xz-utils is now in the system set[3] anyway and .xz instead of .lzma 
 should eliminate some confusion for new users.

 That is about all I can think of. My opinion is that this is mostly a 
 cosmetic change (as lzma is generated via xz-utils anyway) but makes 
 sense given the popular[4] compression choices. I'd like to target 
 2011-04-01 as the date to turn off lzma generation. After generation is 
 turned off, the lzma archives will fall off the mirrors in 7 days. Any 
 concerns?

 Thanks,
 Jeremy

 It makes me sad that you didn't even read my first bullet point :) Yes. 
 We are generating xz snapshots now.
