FreeBSD 10 custom bootonly ISO error

[Rick Miller]

Hi all,

I revisited this thread because I've encountered this yet again, but first
wanted to concretely address the issue described below in term of the ISO's
volume label.  mkisoimages.sh[1] changes the label to upper case before
making it.  See line #39 in the reference.

Now, onto the current problem...below this thread...

I compiled releng/10.0 via release.sh and cp'd an installerconfig into the
resulting ${CHROOTDIR}/usr/obj/bootonly/etc/ directory.  As had been done
previously, ${CHROOTDIR}/usr/src/release/amd64/mkisoimages.sh was run to
re-generate a new bootonly.iso.  The ISO downloads properly and begins to
execute, but produces a mount root error[2].

I re-generated the ISO two different ways...outside the chroot, then inside
the chroot, but the result was the same.  Can anyone provide any guidance
to identify why this has cropped up again despite using the mkisoimages.sh
which corrected the issue previously?
