Is raw IO supported on Linux?

The reason I asked (eventhough there is an answer in the archives) is that sapdb complained that it couldn't read from the device:

2003-04-01 14:18:32  2762     11000 vattach

This was wrong of course, the real problem was that fdisk had a different idea about how large the raw devices were than reality so I overstated the size when adding the devspaces...

Oh well it seems to work now...
