[06:00] Good morning. [18:31] Could someone please tell me what "file /boot/initrd.img*" reports please? [18:32] on a 14.04 its: /boot/initrd.img-3.13.0-62-generic: gzip compressed data, from Unix, last modified: Mon Aug 17 23:21:24 2015 [18:33] No, for 15.10 [18:33] why? [18:33] On my Wily test-bed there's no compression: "/boot/initrd.img-4.1.0-3-lowlatency: ASCII cpio archive (SVR4 with no CRC)" [18:33] i dont have a 15.10 running right now :) [18:34] probably because intel microcode loading is enabled [18:34] in /etc/default/intel-microcode [18:35] since 14.10 I guess [18:36] actually since 15.04 [18:38] Ah, so 'file' is kind-of lying, as in it's a pre-pended early-initramfs image in front of the gzipped image [18:39] I extracted the initrd.img to check some settings and was surprised that only the microcode was present :) [18:40] Good; binwalk knows where it is: "21504 0x5400 gzip compressed data," [18:43] Got it "RD=/boot/initrd.img-4.1.0-3-lowlatency; dd if=$RD bs=$(binwalk $RD | awk '/gzip/{print $1}') skip=1 | file -" ==> "/dev/stdin: gzip compressed data," [18:45] great! was afk for a while :) [18:50] What a pain that cpio has no option to report the size of what it reads; it's an expensive operation processing the file with binwalk [18:59] i have the ubuntu 15.10 willy which was an alpha. is there a newer version out that i should get? [19:02] OK, for completeness: can use cpio as long as we trust/assume block size is 512 bytes: "RD=/boot/initrd.img-4.1.0-3-lowlatency; dd if=$RD bs=$(cpio -t <$RD |& awk '/blocks/{print $1*512}') skip=1 | zcat | cpio -id " [19:07] cpio is always a pita [19:07] it's command line options seem to be designed primarily to confuse === tomaw_ is now known as tomaw === jack is now known as Guest98856 === brainwash_ is now known as brainwash === jack is now known as Guest7598
