device usage problem

[Martin Pala]

Hi,

i figured out during tests on solaris, that solaris statfs() returns 
fake blocks recomputed by using "fundamental filesystem block" (1K). 
This gives bad absolute space usage numbers in present device monitoring 
implementation.

I will repair it on weekend, however because of system dependency 
(nearly every OS has different implementation) i though about splitting 
device code in 'process' stuff like manner - i.e. create new directory 
'device' and appropriate sysdep files. Do you agree?
