Is there a file system for linux that has no permissions? I have a folder that is shared between multiple applications and although they are all running in the same group, I am constantly having permission problems with one application reading what another has written. Since I am using LVM and this is a separate volume, I can format or mount it in any way. I would like a file system that can ignore permissions: i.e. everything is readable and writable by every user on the machine.
Obviously in terms of security I have considered the impact and for my environment it is fine, particularly as it will only be the one partition.
