Bug#551551: live-initramfs: Sid/Squeeze hdd-usb partition not detected in KVM

[Tzafrir Cohen <tzafrir.cohen@xorcom.com>]

Package: live-initramfs
Version: 1.157.4-1

I'm having a problem booting usb-hdd images I build of Squeeze / Sid in
the recent days (haven't tried for a while before that). I'm using
live-helper and live-initramfs from git.

Basically the initramfs loops endlessly trying to find the filesystem to
mount. Originally the symptom was the same as in in #547149 . As of
live-initramfs 1.157.4-1 that error message is gone. But it wasn't the
real issue anyway.

The first this to fix is:

--- a/scripts/live
+++ b/scripts/live
@@ -611,7 +611,7 @@ is_nice_device ()
 {
        sysfs_path="${1#/sys}"

-       if /lib/udev/path_id "${sysfs_path}" | grep -E -q "ID_PATH=(usb|pci-[^-]*-(ide|scsi|usb))"
+       if /lib/udev/path_id "${sysfs_path}" | grep -E -q "ID_PATH=(usb|pci-)"
        then
                return 0
        elif echo "${sysfs_path}" | grep -q '^/block/vd[a-z]$'


Without this /dev/hda1 will not be considered: /dev/hda will be
outright skipped.

This is because the output of /lib/udev/path_id has changed and seems to
no longer include the disk type. I hope this does not introduce any
false positives. See also
http://lists.debian.org/debian-live/2009/10/msg00061.html

Once I got over that I'm stuck with get_fstype from scripts/live-helpers
that fails to find the type. fstype does not seem to detect FAT
filesystems, but I guess that this is not anything new. /lib/udev/vol_id
is missing and hence the last resort '/lib/udev/vol_id -d ${1}' doesn't
help there either.


My build system is Lenny AMD64. My target system is i386:

live-initramfs: 1.157.4-1-2-gdd987ac
live-helper: 1.0.5-2-33-g2b8a748

Config options:

  --arch i386
  --linux-flavours 686
  --syslinux-timeout 20
  --distribution sid
  --packages-lists xfce
  --binary-images usb-hdd
  --bootappend-live quiet
  --apt-recommends disabled


Testing: Any of the following two:

  kvm -hda binary.img
  qemu -hda binary.img
