Livefs/fixit

[Peter Clark]

Hello,

I have a amd64 8.0-RELEASE-P2 FreeBSD box. I was building a spam/av 
gateway. Something has happened and there seems to be some OS 
corruption. I am not sure what did it but symlinks all over the system 
seem to be gone. Links like /home pointing at /usr/home. The data is 
still there in /usr/home/user_blah but the link pointing there is gone. 
There could be more issues that I have not discovered yet. I would like 
to repair the base os from the 8.0 DVD. I believe I should use the 
livecd/fixit method. Is this the right way to go about doing this? Are 
there some concise instructions for this? Will this affect the installed 
ports, ie. things like getting rid of all the configs in /usr/local/etc, 
rc.conf, passwd, /etc/groups ? I imagine I will need to reinstall all 
the ports like one would do after a buildworld.

Any help would be appreciated.

Peter
