Description Richard W.M. Jones 2013-11-22 14:24:50 UTC

Description of problem:

For x86 (doesn't work on ARM) it should be possible to guess the
module path from just a "naked" vmlinuz file.  This is because
the vmlinuz file contains its own version number.

supermin-helper already contains code to look for this version
number, but it doesn't work if you set only SUPERMIN_KERNEL
environment variable:

  select kernel /dev/.initramfs/live/vmlinuz0
  supermin-helper: cannot guess module path.

There is a possibly superfluous test in helper/kernel.c:
create_kernel_from_env which stops this from working.  It
should be possible to fix this fairly easily.

Version-Release number of selected component (if applicable):

febootstrap in RHEL 6.4
also likely affects supermin upstream

This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle.
Changing version to '22'.
