OK, But your issue is not related to me.
I can reproduce my issue by two simple script.
If tar is deciding that the file has "changed" just because the link
count on the dentry has increased, that sounds like it is probably a bug
in tar and ought to be fixed there.
That said, I can't immediately think why autotools_copy_aclocal couldn't
use a symlink rather than a hard link which would avoid this whole
problem. If the file is in the sysroot then there should be no risk of
it going away underneath its user.
Sadly this doesn't work. We block copy a set of .m4 files from the
sysroot. We can be running do_configure of package A whilst package B is
de-installed from the sysroot and this leads to files disappearing
whilst they're being accessed. Its turned out to be a really awkward
problem to fix.
Do we need some kind of a read/write lock on accessing those files. (Is this
even something that we can do easily though the existing mechanisms?)
It would kill performance for no good reason, been there, looked at
it...
Cheers,
Richard
I think reverting the below optimization maybe better than using lock

scripts/cp-noerror: Try and use hardlinks if possible
Since we generally have lots of copies of the directories created
using this tool, use
hardlinks where possible. This should save a little disk space and
improve performance
slightly.
