Description Austin S. Hemmelgarn 2015-07-01 17:58:36 UTC

Created attachment 406038 [details]
Patch for gen_initramfs.sh to add LZ4 compression support.

The kernel has had support for LZ4 compressed initial ram file-systems for some time now.  Such compression provides less space savings than LZO, but is significantly faster both compressing and decompressing (and the decompression time is independent of the compression level), and as such can lead to noticably faster boot times on systems with fast storage.

The attached patch (which is only lightly tested) adds such support to gen_initramfs.sh.
