Some implementations of cp can't create hardlinks (replaces 'cp -al' on Linux):
|

Prepare repo r1:
|
|
|
|
|
|
$ hg init r1

$ echo c1 > f1

$ hg clone -U --debug r1 r2 --config progress.debug=true

Create hardlinked copy r4 of r3 (on Linux, we would call 'cp -al'):

|
'checklink' is produced by hardlinking a symlink, which is undefined whether
|
|
|
the symlink should be followed or not. It does behave differently on Linux and
|
|
|
BSD. Just remove it so the test pass on both platforms.
|
|
|
|
|
|
$ rm -f r4/.hg/cache/checklink
