Public bug reported:
in ubuntu14, the behavior of "ln --relative" seems to be quite broken.
on ubuntu 16 it works as expected. can we please backport whatever fix
from u16 or update coreutils? 8.15 is where they started including the
'realpath' binary, maybe they fixed "ln --relative" too.
u14 INCORRECT:
$ loop=0; nloops=4; base=/tmp/lntest; rm -rf $base/ && mkdir -p $base/dir &&
touch $base/dir/file && while ((loop++ < nloops)); do ln -frs $base/dir/file
$base/link; readlink -f $base/link; sleep 1; done
/tmp/lntest/dir/file
/tmp/lntest/file
/tmp/lntest/dir/file
/tmp/lntest/file
u16 CORRECT:
$ loop=0; nloops=4; base=/tmp/lntest; rm -rf $base/ && mkdir -p $base/dir &&
touch $base/dir/file && while ((loop++ < nloops)); do ln -frs $base/dir/file
$base/link; readlink -f $base/link; sleep 1; done
