# to install Automotive Grade Linux (AGL) on Minnowboard and any PC with UEFI boot
#
# changes
# - keep initrd if present
# - create a grub config with PARTUID to ease boot from various devices automaticaly
# - add a UEFI startup.nsh script for autoboot
-# - does not allocate swap
-#
+# - remove any configured swap is fstab
+# - accept .hddimg, wic and wic.xz as sources
