Patch: [PATCH 04/17] bootwrapper: Make compression of the kernel image optional.

[Milton Miller]

You missed two .gz in the code, which would result in ineffective caching.
Found by inspection.

-if [ -z "$cacheit" -o ! -f "$vmz.gz" -o "$vmz.gz" -ot "$kernel" ]; then
+if [ -z "$cacheit" -o ! -f "$vmz$gzip" -o "$vmz$gzip" -ot "$kernel" ]; then

You also need to add these generated files to clean-files in the Makefile.
