That brings me to the following question regarding DEV_BSIZE (see 
discusstion earlier on tech-kern):

Is the wedge system to provide a new interface for filingsystems to disc 
devices or wouldn't that be preferable?

Wouldn't it then be the time to also scrap the fixed DEV_BSIZE blocksize 
interface to discs to replace it with a *sector-size* oriented interface so 
various filingsystems like msdosfs and udf eventually can support non 512 
bytes/sector filingsystems?

There has been several patches around for yonks that fixes these issues but 
they were never integrated. Our msdosfs f.e. doesn't support non 512 
bytes/sector devices. Filingsystems DO change on sectorsize and devices 
like DVD/CD+-(M)R(W) can't just do read-modify-write cycle to cope with 
blocksizes smaller than the sector size.

Regards,
Reinoud
