Ooh ooh! are there any filesystems @ present that support copy on write?
Seems like a very useful feature that would be relatively easy to
implement (just
store a hash for each file in it's inode). With the ammount of duplicate
files on my
system (see freshmeat.net/projects/fslint) it would be very useful.
write() already
supports ENOSPC because of holes in files etc. There would be large
overhead
though as the hash for a file would have to be generated on each write()
? For a
"revision control" filesystem it would probably be more appropriate to
work @ the
block level instead? Hmm snapFS be appropriate for this ?
