Re: [Xen-devel] xen Makefile being nasty with EXTRAVERSION
Yeah, playing with the directory name is gross!
I'm trying out replacing this with:
XENVERSION ?= -xen
EXTRAVERSION := $(EXTRAVERSION)$(XENVERSION)
I've then changed the repository makefile to override XENVERSION with
-xenU or -xen0 as appropriate. If it works as expected I'll check it
in.
