snv_133 and terminal repair before first login.

If you were upgrading to the latest development release (greater then 125, currently 133 as of 20100221) it could happen that working in a shell or by accessing machine remotely (SSH) does not work. It is required that before booting in the new Boot Environment (BE) you set up the shell in new BE, form existing BE, by mounting new BE, and it could be done with following commands:

Boot into the previous BE and correct /etc/minor_perm file,
following instructions:

$ pfexec beadm list
$ pfexec beadm mount NameOfNewBE /mnt
$ pfexec sh -c "grep ^clone: /etc/minor_perm >> /mnt/etc/minor_perm"
$ pfexec touch /mnt/reconfigure
$ pfexec bootadm update-archive -R /mnt
$ pfexec beadm unmount NameOfNewBE


After that you can boot into the new BE.
