Geom version/generation sysctl

[Soeren Straarup]

Hi

I'm looking for a way to have a version/generation sysctl value.
one way i could do this is:
sysct -b kern.geom.confxml > file_a

sleep for some time
sysct -b kern.geom.confxml > file_b
diff file_a file_b | wc -l

If the last line is zero then do nothing. And then repeat it.

What i'm looking for a cheap way to get around this, with a version/
generation number that i test on.

Would something like that be hard to implement?
