I need some help. I'm trying to do some research on user definable semantics
on a file system in UNIX, and I am having problems finding information.

What I am trying to do is add operations to files. For example, if I wanted
a file to be compacted, I would hang a compaction operation off the file and
whenever the file was accessed the compaction process would be activated
and the data in the file would be uncompacted, that's a read, and to write
compaction would take place before the write was performed.

If anyone has any information that the think might be useful, please send it
my way.

Thanks in advance
