Hi

I have an application where I want to make relatively frequent copies of 
a large file, and the copies will remain largely similar to the original.

It seems to me that a file-level copy-on-write would support this well.

So, does reiserfs support anything like this?

If not, can I implement this easily (how easily ;) ) with a plugin.

Any ideas and pointers greatfully received
Thanks
Roland
