Attempting to respond to several messages here.....
The devel part of the various user space packages is included in the
one source package, it is just a different build target. If you use
the Makepkg script it builds the devel rpms, if you just use make
there is an install-dev target.
You said that you had implemented the system calls for acls and
extended attributes for the powerpc platform, I presume you have the
user space changes as well so that the library calls in the acl
package work. I would concentrate on getting the chacl command
to work in all modes before moving to xfsdump/restore. Make sure
that the system call numbers at the end of acl/libacl/acl.c are
defined correctly for the ppc.
Finally make sure you are linking xfsdump with the modified libacl.
OK, mostly fairly obvious stuff.
Oh, and when you have kernel and user space working for ppc, can you
send in a patch so we can add the support to the packages on oss.
