hehe, pitaj google za "ufs_read_super: fs_bsize 16384 != {4096, 8192, 32768}"
da vidish kolko vryzki ste ti izplue (vkl. na english i greek ;-), no vsi4ki 
so4at kym tozi patch.

qvno UFS driver-a za linux e pisan kogato i freebsd ne e imal block size = 
16384. Tova e OK. No vnimavaj s writes pod linux vyrhu UFS 44BSD dqlove, 
ponezhe vse oste e dangerous ;-) . Az sym si skapval nqkolko ... osven tova 
tozi driver ne poddyrzha Soft Updates, a neznam dali poddyrzha i FFS (Fast 
File System, to bi trqbvalo da si e v specifikaciqta na UFS 44BSD, ama ne 
znam). Kakto i da e systezanieto e mezhdu dva podhoda:
-sinhronna rabota s fs-a + SU+FFS, pri FreeBSD, 
(pri OpenBSD SoftUpdates sa experimental oste, pri NetBSD maj sa production)
drugoto e:
- async rabota s fs-sa i Journaling - Linux i Commercial Unices.

ami obsto vzeto az imah problemi samo kogato prepylnq UFS-a pishejki po nego 
pod Linux i posle nikoj neiskashe da go mountira i popravq. 

Naj-dobre pitaj avtora na drivera za linux. Note: tozi driver se opitva da 
poddyrzha vsi4ki UFS types kojto sa v obryshtenie. Uspeh ;-)
