Make a failing cross-partition mv give a sensible diagnostic.
A cross-partition move of a file in a sticky tmpdir and owned by
another user would evoke an invalid diagnostic after copying it:
mv: cannot remove `x': Operation not permitted
Either of the following (mv.c, remove.c) changes would fix the bug by
itself. I think it's slightly better to use both; the added cost is
minimal: mv: an extra lstat-per-mv-cmdline-arg-that-goes-cross-partition,
rm: an extra lstat-per-unlink-that-fails-w/EPERM.
* src/remove.c (remove_entry): Also lstat the file upon EPERM.
* src/mv.c (rm_option_init): Initialize root_dev_ino just as is done
in rm, so that a cross-partition invoked remove.c:rm call works the
same way as one invoked from the command-line use of "rm". That
setting of root_dev_ino makes rm() do the equivalent of an additional
lstat for each argument, which in turn gives rm enough information to
issue the right diagnostic.
* tests/mv/sticky-to-xpart (version): New file. Test for the above.
* tests/mv/Makefile.am (TESTS): Add sticky-to-xpart.
Arrange for "make check-root" to run the new root-only test.
* tests/Makefile.am (tb): New target, to run the new root-only test.
(all_t): Add tb.
* src/c99-to-c89.diff: Adjust offsets.
