Yes. Maybe it isn't good to give so clear recommendation for LZO over gzip here. I think it is still safe to say that gzip and LZO are better than bzip2, XZ, or LZMA for compressing a kernel that will be loaded from a normal hard disk. It would be unusual if reading the disk was so slow that e.g. XZ would make the booting faster than gzip. -- Lasse Collin | IRC: Larhzu @ IRCnet & Freenode
