Hi, now that upstream linux-2.6 kernels support xz-compressed ramdisks, I would like update-initramfs to support generating them.
This minimal patch WORKS FOR ME: $ sed '/lzop/ {p; s/lzop/xz/g; }' /usr/sbin/mkinitramfs | diff -pud /usr/sbin/mkinitramfs - --- /usr/sbin/mkinitramfs 2010-09-27 20:46:10.000000000 +1000 +++ - 2011-02-17 01:41:52.028878435 +1100 @@ -148,6 +148,7 @@ if ! `grep -q -i ^config_rd_${COMPRESS%p fi [ "${compress}" = lzop ] && compress="lzop -9" +[ "${compress}" = xz ] && compress="xz -9" if [ -d "${outfile}" ]; then echo "${outfile} is a directory" >&2 At least this far: $ file -s /var/tmp/cdeboo*/boot/initr* /var/tmp/cdebootstrap-amd64~/boot/initrd.img-2.6.38-rc5: gzip compressed data, from Unix, last modified: Thu Feb 17 01:25:54 2011 /var/tmp/cdebootstrap-amd64/boot/initrd.img-2.6.38-rc5: xz compressed data I haven't actually tried booting it yet, and obviously updating the documentation is left as an exercise for the reader. PS: xz has an -e option for "compress me harder". Given the compress/decompress ratio for ramdisks (i.e. once vs. every boot), it might be advisable to do "xz -9e" instead of the "xz -9" above. -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
