Kernel recompilation and mkinitcpio questions
Hello,
I'd like to know whether it is necessary to recompile the kernel with command, 'mkinitcpio -p kernel26' after removing HOOKS and changing the kernel.img compression method in '/etc/mkinitcpio.conf' and and/or changing settings in '/boot/menu/grub.lst'.
(A few more questions)
Is kernel compression recommended?
Would 'gzip' be faster at decompressing, compared with 'lzma' and 'bzip'?
I understand that compression reduces HDD read/write at the expense of more CPU commit, but does this affect boot-time at all?

Yes, you should run

I did some benchmarks and LZMA decompress a bit faster than Gzip, but compression is much slower while generating an image.
