All it takes is somebody to rewrite cd9660 to be a r/w filesystem :-) It's not trivial though, because iso 9660 is essentially a sequential archive with a index up front, so if you change the size of one file all the ones after it move as well. I guess as long as you don't want to make any files longer it would be relatively possible. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk_at_FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.Received on Wed Apr 06 2005 - 08:55:37 UTC
