The quickest initramfs, assuming that ALL kernel modules you need to boot are already compiled into your kernel: genkernel --install --no-ramdisk-modules initramfs
Plus optionally, If you know you don't need any of these, include this to make it really get much smaller: --no-lvm --no-mdadm --no-dmraid --no-multipath --no-iscsi --no-disklabel --no-firmware --no-zfs --no-gpg --no-luks --disklabel is the one that most users will probably need, if they use LABEL= or UUID= arguments in your fstab. That will give you an initramfs of scripts + busybox. On my box, it's about 724KiB. -- Robin Hugh Johnson Gentoo Linux: Developer, Trustee & Infrastructure Lead E-Mail : robb...@gentoo.org GnuPG FP : 11ACBA4F 4778E3F6 E4EDF38E B27B944E 34884E85
