Yes, this could be. But...

Yes, I found the same thing last night. You can use hfspax to make a
cpio archive, and cpio archives have no path-size limitation. 

I could also make a ustar archive, which has a pretty hefty size
limitation 250 characters. 

The only minor problem is that I can't use pax to read from a list 
containing file names, as I can with tar:

tar -T file_of_names -f archive.tar

pax -w -f archive.pax ???

I have come up with this very satisfactory, but not pefect solution:

cat file_of_names | pax -w -x cpio -f archive.pax


The more I can keep with the original syntax, the less lines I will
have to change.

Thanks

Paul
