[elbe-devel] [PATCH 1/3] finetuning: Add image partition shell action

[Olivier Dion]

Scripts defined under nodes losetup/sh are written to
builddir/finetuning-lostup-sh-%d, where %d is the partition number of
the image.  They are then executed with ELBE_MNT set to the mount
point of the target partition.
