Dear fellow users,
I want to pose a quick questions. I know Mr. A Robatino posts deltaisos regularly which amounts to a certain amount of savings when one downloads a deltaiso. Although I have never downloaded one, I ask if one can save more bandwidth if we use lzma compression. I ask this question because TeXLive2009 comes in a iso.xz format which is lzma compression and saves some bandwidth. Would Fedora welcome such savings and distributing isos, whether test or official releases as lzma compressed?
Has this been thought of before?
For the Live images you can keep an eye on the proposed feature page: https://fedoraproject.org/wiki/Features/LZMA_for_Live_Images
Current status is that support in the 2.6.34 kernel is iffy. Linus bounced Lougher's initial pull request and only some clean up pacthes were accepted before the merge window closed. Potentially he might pull in a patch providing support for lmza squashfs later since there was an initial pull request in time and it sat in linux-next for essentially all of 2.6.33 development, but I wouldn't bet the farm on that.
I did test an lzma compressed live image (non-functional due to no kernel support) for the games spin and found it was 10% (400 MiB) smaller than the zlib compressed version.
