NetBSD zaphod 2.1 NetBSD 2.1 (GENERIC) #0: Mon Oct 24 22:35:45 UTC 2005  jmc@faith.netbsd.org:/home/builds/ab/netbsd-2-1-RELEASE/i386/200510241747Z-obj/home/builds/ab/netbsd-2-1-RELEASE/src/sys/arch/i386/compile/GENERIC i386

>Description:
Backing up to DVD:

Immediately, gtar(1) complains the deprecated use of the "l" option and suggests using "--one-file-system" instead.  Then things seem to go fine until it comes time to write out the newly-created tarball to the burner with cdrecord(8).  cdrecord(8) aborts, thus causing cdbkup(1) to also abort.  Here are the two lines of interest.

/usr/pkg/bin/cdrecord: Track 1 has unknown length.
/usr/pkg/bin/cdrecord: Use tsize= option in SAO mode to specify track size.


>How-To-Repeat:
cdbkup 0 -s 4 -l home -S 4200000000 -c none -w /usr/tmp/cdworkdir /dev/rcd0d /usr/home/joe

The home directory in question contains about 20 gigs of stuff.
>Fix:
The following patches seem to fix things completely:
