I recently discovered an interesting “feature” of symbolic links in conjunction with NFS mounts: they don’t work!
For example, let’s say you have the following NFS export:
Inside of that export, you have the following path:
In *this* directory, you have a symlink called ‘
current‘, which points to a different location:
current -> /media/osmedia/linux/ubuntu/11.10
Here’s the rub: if anyone tries to mount the root (or sub path) of that NFS export (say
/media/files/isos/osmedia) at a local point (say,
/mnt/osmedia), the symlink will fail to work correctlyÂ because there is no path
/media/osmedia/linux/ubuntu/11.10 on the local machine!
That’s not cool.
Here is another case where bind mounts will save your bacon!
Instead of using symlinks on the NFS host, use bind mounts – that way the path will still workÂ when exported.
