[Bug 941874] Re: (fakeraid) root device not activated during boot

[luckymae]

This is because Ubuntu is a piece of shite time waster, worse than
Windows 98 and Windows 3.1. You want something solid don't go with a
distro that places importance on new themes instead of stability. It
will be 2019 and Ubuntu team will still try to fix these bugs. They're
worse than Microsoft and you'll be sorry you wasted your time on half-
arsed applications that segfaulted and an install system that cannot
detect intel raid when other distro can. rm -rf /*

What a waste of my effing time this stupid wannabe open source
programmers. Go fix these and back to your mommy's basement where
Richard Stallman will pay you tons of money (ohhh wait .. he's only
collecting the money for himself). Sucks to be you open sourze
perogiemerz.

Title:
  (fakeraid) root device not activated during boot

Status in “dmraid” package in Ubuntu:
  Fix Released
Status in “multipath-tools” package in Ubuntu:
  Fix Released

Bug description:
  I have installed Precise Pangolin Alpha 2 to a fakeraid stripe, but
  ubuntu fails to boot after install. When choosing recovery option, the
  boot process times out waiting for root device and drops to busybox
  shell. Running "dmraid -ay" and exiting busybox resumes boot and it
  continues normally.

  The problems are:

  * There are no initramfs hooks for kpartx, so kpartx is not available during boot.
  the following files are needed:
  /sbin/kpartx
  /lib/udev/kpartx_id
  /lib/udev/dmsetup_env
  /lib/udev/rules.d/95-kpartx.rules

  * The hook for dmraid udev rules is wrong:
  The script /usr/share/initramfs-tools/hooks/dmraid
  tries to add:
  /lib/udev/rules.d/85-dmraid.rules
  but the existing file is called:
  /lib/udev/rules.d/97-dmraid.rules

  After fixing the above two issues, system boots normally.

  * dmraid-activate is sometimes called with full device name
  dmraid-activate expecte device name withouth "/dev/", e.g. "sda" not "/dev/sda". However the script
  /usr/share/initramfs-tools/scripts/local-top/dmraid
  calls dmraid-activate using the full device name and path.

  * There might also be antoher bug on line 100 in dmraid-activate (in the awk script):
      # Heximal to decimal conversion array
      for (i = 0; i <= 9; i++) hex2dec[i] = i
      hex2dec["a"] = 10; hex2dec["b"] = 11; hex2dec["c"] = 12
      hex2dec["e"] = 13; hex2dec["d"] = 14; hex2dec["f"] = 15;
  Element "e" and "d" appears to have been switched. I'm not entirely sure what the script is trying to do though, and that part of the script does not affect my system.
