The 'all' and 'initrd' arguments build the initramfs, as in genkernel all genkernel initrd Yes, the initrd argument does indeed build an initramfs and not an initrd.... And the OP should keep in mind that the initrd format was dumped many many kernel versions ago and these days we use initramfs, > grub/lilo/xen loads an initramfs exactly the same as an initrd -- the > kernel determines how to use the uncompressed data by looking for a > cpio header. > > > Yes, start with kernel documentation ... but something quicker ??? > > :-) > > Not that I've found. True. The only sane docs around I've ever found about this is Documentation/earlyuserspace.txt - it's a tough read, but it's all there alan -- Optimists say the glass is half full, Pessimists say the glass is half empty, Developers say wtf is the glass twice as big as it needs to be?
