disklabel from sysinstall

[Matthew Herzog]

Hi All.

Just wondering if anyone has noticed the following problem on Sparc64
FreeBSD STABLE.

When I partition a disk from the postinstall disklabel option and then
exit the sysinstall shell
I am left in an environment where I have no access to any binaries nor
can I login  via ssh from
another host. Sysinstall seems to have unmounted all my file systems.
For example if I type, "ls"
I get "ls: not found".

I should mention  that I  ran sysinstall  from a  /usr/local/bin/screen
session in the latest instance.
I end up having to punch the power to regain access. Can anyone explain
why this happens and or
what I can do to avoid it? I mean aside from using disklabel that is :)
I'm fairly sure I have encountered
this behaviour while in a regular shell in single user mode too.

Thanks.
