Nomer zhestkogo diska sovpadaet s ego SCSI-nomerom.
Vnutrennij disk - obychno nomer 3, pervyj vneshnij disk - 0
Disk razbivaetsya na razdely - do 7 shtuk, razdely numeruyutsya
bukvami a-h. Razdel "c" oboznachaet ves' zhestkij disk. Root
polozheno klasst' na razdel "a", swap - na "b"
/dev/sd
/dev/sd3a - kornevaya fajlovaya sistema
/dev/sd3b - swap-oblast'
/dev/rsd3c - zhestkij disk celikom
Geometriya diska dolzhna byt' opisana v fajle /etc/format.dat
