Subject: [PATCH] build-vm, kernel, uboot: return possibility of changing boot
 sequence of kernels
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since packet sorting is enabled by default, then
the order in KFLAVORS has ceased to matter.
Kernels are always installed in alphabetical order.
Therefore, it makes no sense to sort by buildtime.
See-also: https://bugzilla.altlinux.org/show_bug.cgi?id=30806

Also fixed my typo. When creating a symlink, the variable
$kver was used, i.e. the entire list of kernels, not the
last value $KVER of the list.
