compression in dump(8)

[Swift Griggs <swiftgriggs%gmail.com@localhost>]

I notice that the dump command in NetBSD doesn't feature the use of any 
internal compression. If one compresses the dump file, then you can't use 
it as the basis for a restore. 

Is that because the compression functions aren't in libc (ie.. they are 
off in libz or liblzma) ? Perhaps it's just a matter of someone doing the 
work ? It'd be a big help for admins who want to be able to use a modern 
compression algorithm without having to uncompress the dump to use it. I 
for one, would use it on all my systems.
