@martinezjavier I think you wrote this code, could we borrow your eyes for a quick review? |

It might be better if we changed the scope of this variable into the for loop, like the "index_suffix" variable.

@ericcurtin Thanks. I've refreshed this PR.
When doing a full copy of:
$deployment/usr/lib/ostree-boot -> /boot/ostree/$os-$bootcsum/
U-Boot bootscript can use the 'bootdir' to find, for example,
the Device Tree (dtb) file, as in:
load ${dtype} ${disk}:${bootpart} ${a_fdt} ${bootdir}${dtbname}
Or u-boot external bootscript:
load ${dtype} ${disk}:${bootpart} ${a_scr} ${bootdir}${scriptname}
It could also be possible to point 'bootdir' directly to the
$deployment/usr/lib/ostree-boot, but this would add unnecessary
restrictions on what file system can be used for rootfs as u-boot,
for example, can not read from BTRFS. So having
bootdir=/boot/ostree/$os-$bootcsum/ is a better approach here, as
/boot can be on a separate partition with its own file system type.
