Check the boot log itself; you may want to get rid of the sysinstall,
so that it doesn't clear the screen, or have it emit 25+ LF before it
starts its thing, to ensure that all the console messages are thus
available via scroll-lock.

One possible source of a problem could be the GEOM changes to change
the xx0c to xx0 instead, removign legacy support for xx0c; in that
case, the root remount attempt fromt he device in /etc/fstab  is
probably referencing the old name instead of the new name (a good
reason to *never* change device names, unless the old names offend
thing God), so the root remount never happened, leaving the root
read-only.

No, it was an expected result of the change in device names from
use of GEOM.  I pointed this out on the -current list almost a
month ago, and made specific reference to "live FS" and "PicoBSD"
and "Bootable CDROM" (the other places I expect you will now see
this problem).
