Znovu opakuji: root muze absolutne vsechno. Pokud se vam to 
nelibi, pouzijte nejaky vyrazne odlisny operacni system (nic POSIX-
like, a nemyslim ani W2k apod.). A, kdyz uz jsme u toho, ani to 
nesmite mit zalozene na platforme PC, protoze tam misto 
procesoru muze "root" dat emulator procesoru, ze?

Jaky problem se snazite vyresit?
