Thank you for the prompt response. Yes, I'm using autofs4 which came with CentOS release 4.6
mount -V mount: mount-2.12a Is that version of mount OK or do I need a newer version to work with the locking path? If I need a newer version can you please let me know approximately which one? Lastly, does autofs5 not have this issue?
