Description Joey Boggs 2009-08-13 14:33:25 EDT
Description of problem:
When creating a livecd based image with a symlink from /etc/mtab to /proc/mounts it is removed during the build process

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

How reproducible:
Any kickstart that symlinks /etc/mtab to /proc/mounts

Actual results:
/etc/mtab -> /proc/mounts is removed 

Expected results:
/etc/mtab -> /proc/mounts still intact

Additional info:

Under the ImageCreator class in creator.py

If you comment out:  os.unlink(self._instroot + "/etc/mtab") the symlink is left intact. I'm not entirely sure of the case for it being removed but maybe a check to see if the link was created by something other than livecd-creator and leave intact if so.

    def unmount(self):
        """Unmounts the target filesystem.

        The ImageCreator class detaches the system from the install root, but
        other subclasses may also detach the loopback mounted filesystem image
        from the install root.

            os.unlink(self._instroot + "/etc/mtab")
        except OSError:

There's no way really to tell if it was created otherwise -- livecd-creator always does create it

What's the use case you have for wanting it on the later image?
