Please push the mtd-utils-1.4.3-1 or öater update to F15 as well. The current package in F15 fails to build and the armv7 bootstrap needs a working F15 source package to build from.
It's been pushed to pkg git and built. Do you really need it pushed into f15-updates?
I do not thing we strictly need it pushed as an update no, but if there is any difference in functionality then it is preferred to avoid functionality to differ between the architectures.
The updated package built fine on arm.
