Subject: (copy_internal): Treat src and dest as the `same' in
X-Git-Tag: FILEUTILS-4_0j-trial~29
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=1b6c640f464fe3bf8b2923d5be4e6d30460794f5;p=thirdparty%2Fcoreutils.git

(copy_internal): Treat src and dest as the `same' in
`mv src symlink-to-src' when src and dest are on different partitions.
Otherwise, that `mv' command would silently remove `src'.
Reported by Michael Stone.
