WARNING:  This is not a published interface, it is a stopgap measure for

b7e23599cf Reduce the GEOM verbosity under bootverbose to something more sufferable. 
This is not quite the set of information I would want, but the tree where
I have the "correct" version is messed up with conflicts.

af63f9546a Now that the sectorsize and mediasize are properties of the provider, 
don't take the detour over the I/O path to discover them using getattr(),
we can just pick them out directly.

Do note though, that for now they are only valid after the first open
of the underlying disk device due compatibility with the old disk_create()
API.  This will change in the future so they will always be valid.

bd4b849139 Add the new g_slice_config() call, which can add/delete/change a slice, 
with support for trying, doing and forcing.

This will eventually replace g_slice_addslice() which gets changed from
grabbing topology to requing it in this commit as well.

4509f96cc5 Make kernel dumps work with GEOM. 
Notice that if the device on which the dump is set is destroyed for
any reason, the dump setting is lost.  This in particular will
happen in the case of spoilage.  For instance if you set dump on
ad0s1b and open ad0 for writing, ad0s* will be spoilt and the dump
setting lost.  See geom(4) for more about spoiling.

3e53a43775 First commit of the GEOM subsystem to make it easier for people to 
test and play with this.

This is not yet production quality and should be run only on dedicated
test boxes.

For people who want to develop transformations for GEOM there exist a
set of shims to run geom in userland (ask phk@freebsd.org).

Reports of all kinds to: phk@freebsd.org
Please include in report:
        dmesg
        sysctl debug.geomdot
        sysctl debug.geomconf

Known significant limitations:
        no kernel dump facility.
        ioctls severely restricted.
