Description Russell Stuart 2003-03-19 07:38:36 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20021224

Description of problem:
This command:
  cp --archive --one-file-system --verbose src dst
fails if the directory src contains a mount point
mounted with 'mount --bind'.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
Run these commands as root:
  mkdir -p src/{x,y}
  mount --bind src/x src/y
  cp --archive --one-file-system src dst

Actual Results:  The cp command exits with a status of 1
and gives the error message:
  cp: will not create hard link `dst/y' to directory `dst/x'
This directory structure is created:
Note: there is no dst/y.

Expected Results:
1. cp should give no error messages.
2. cp should have an exit status of 0.
3. cp should create the directories dst/, dst/x/ and dst/y/.

FWIW, rsync seems to behave correctly in this situation.
