RE: [Xen-ia64-devel] How to clean xenlinux-ia64-2.6.12.hg?

Thanks, this looks like a good addition.  However my
problem was different... I neglected to specify a
fully-qualified pathname for XEN_PATH so the resulting
output and softlinks were very confused.

Perhaps the following from xenlinux/arch/ia64/Makefile:

        [ -e include/asm-xen/asm ] \
         || ln -s asm-ia64 include/asm-xen/asm
        [ -e include/asm-xen/xen-public ] \
         || ln -s $(XEN_PATH)/xen/include/public \
                include/asm-xen/xen-public
        [ -e include/asm-ia64/xen/asm-xsi-offsets.h ] \
         || ln -s $(XEN_PATH)/xen/include/asm-ia64/asm-xsi-offsets.h \
                include/asm-ia64/xen/asm-xsi-offsets.h
 
should instead be moved into a xenlinux/arch/ia64/xen/mkprep
script which could be made more robust, e.g. should check
that the links are made to real files.  I can imagine
that with this new interdependency between the xenlinux
directory and the xen directory, not having the directories
in the right places (relative to each other) would be a
very common error and -- speaking from experience -- the
fix is not at all obvious.

In fact, the execution of mkprep probably should be done
in xenlinux/arch/ia64/xen/Makefile.  (And can the
CLEAN_FILES addition then be moved there as well?)

Any script/Makefile experts want to give this a shot?

Thanks,
Dan
