So we could use tar, with the following super ugly (and likely not very
portable) formulation:
diff --git a/Makefile.inc1 b/Makefile.inc1

On the zfs-on-root system I looked for one (of the few) files without uarch not
set and used cp to copy it to root's home dir. The copy has uarch set.

Btw tar does not complain if it cannot set flags, although it does set them if
possible (but not on NFS, obviously).

On two machines with /usr/bin/basename on UFS, the uarch bit is not set. On one
machine with a ZFS root, uarch is set on /usr/bin/basename.

We still still don't know why the flags are set on /bin/basename... Until I
understand where they are coming from, or what environment we see them, I'm

How about doing the copy only if the existing target differs from the source?
Something like "cmp -s a b || cp a b". Would that be sufficient to satisfy

The -p change was to fix meta mode. Now that I've had a chance to sleep on it
I remember: it was for metamode. filemon catches EVERYTHING that's used to
build a target, including the binaries that are

Could this be related to bug 249957? - There seem to be races in what make is
doing when timestamps are either truncated to seconds (over NFS) or

But the best way to fix this would be to import NetBSD's cp's -N flag: don't
copy flags. We don't need them. And I can think of no good that can come from
copying them...
Though I'd really like to

Iirc, copying without -p would not preserve the file's times, which lead to
some dependency breaking. Removing that will break things again. Iirc, there
were other problems fixed that were discovered

Given that commit, I am rather hesitant to say we should just go ahead and drop
the -p without first understanding why it was needed in the first place.

Alex, Jess - it seems reasonable to me to copy host tools without -p; I'm happy
to land this patch if you agree.
Martin, would you attach a git format patch so that author metadata can be
preserved?

The root cause probably is that files such as /usr/bin/basename have uarch set
in stable/14, but not in releng/12.4.
