Pokial spravne vidim, root particiu nemas na NFS ale na /dev/hda1.
Je to spravne? Co vlastne chces natiahnut z NFS? Kernet asi nie,
ten ti funguje spravne (a aj tak sa zvycajne taha z TFTP), root mas na hda1.

Toto vyzera byt vporiadku vzhladom na boot riadok.

Ak by si nahodou chcel cez NFS root particiu, tak zapni aj poslednu
