nothing delete, nothing has been removed...
after I finished installing, i logon and everything was ok... than I logon using PuTTY from another PC with "wheel group" user account and switch to "root" using "su"... I tried to install Apache server, but for a moment I quit "root" typing "exit" and after that I can't to anything under "root", aether from console or remote PC...
something to do or to reinstall? this is fresh and my first freebsd installation. there is no problem to install os again.. but, it will be nice to now what happend and how can correct that... just for further using...
p.s. sorry for bad english...
