This apparently interacts poorly with grub2-mkconfig's title generation and causes weird errors, so it's not ready yet. This commit also fixes some quoting errors in the dtbdir n-k-p code. Resolves: rhbz#1153410 Resolves: rhbz#1088933 Signed-off-by: Peter Jones <pjones@redhat.com>

Subject: [PATCH 01/10] Don't go past the last element of indexVars in
|
|
findEntryByPath
|
|
|
|
We add a chance of creating an infinite loop, because we
|
|
were reading memory past the last element of indexVars set to -1.
|
|
|
|
This issue was only apparent with -O2, probably because the way the
|
|
memory was initialized.
