Thanks Adam. I tried mkisofs, but ran into problems with RockRidge: mkisofs: Error: goo/boot/boot0 and zim/boot/boot0 have the same Rock Ridge name mkisofs: Error: goo/boot/boot0 and gir/boot/boot0 have the same Rock Ridge name mkisofs: Error: zim/boot/boot0 and gir/boot/boot0 have the same Rock Ridge name I can't find a solution to these name clashes, and IMAP maildirs have hundreds of similar names, which is likely to be even worse. So I'm trying to use FFS instead, on the basis that it does this natively and doesn't have to deal with iso9660. crackula is pretty cool too :-) ----- Original Message ----- From: "Adam Weinberger" <adam@vectors.cx> To: "Rob" <listone@deathbeforedecaf.net> Cc: <freebsd-questions@FreeBSD.ORG> Sent: Monday, July 15, 2002 3:10 AM Subject: Re: FFS on CD-ROM - can it be done? > easiest way to get stuff on a cd is with mkisofs(8) from > ports/sysutils/mkisofs. > > with what you've used, you can read from the disk raw, like > dd if=/dev/racd1c of=file.iso > or just cp /dev/acd1c . > > check out http://www.freebsd.org/doc/handbook/creating-cds.html > > nice domain name ::) > > -Adam > > > >> (07.14.2002 @ 0522 PST): Rob said, in 1.6K: << > > Wise Ones, > > > > I'm trying to put a FFS filesystem on CD-ROM.
