* Introduce the concept of "magic spaces", and implement them in most ofphk2002-05-211-0/+30
| | | | | | | | | | | | | | | | the relevant classes. Some methods may implement various "magic spaces", this is reserved or magic areas on the disk, set a side for various and sundry purposes. A good example is the BSD disklabel and boot code on i386 which occupies a total of four magic spaces: boot1, the disklabel, the padding behind the disklabel and boot2. The reason we don't simply tell people to write the appropriate stuff on the underlying device is that (some of) the magic spaces might be real-time modifiable. It is for instance possible to change a disklabel while partitions are open, provided the open partitions do not get trampled in the process. Sponsored by: DARPA & NAI Labs.

* Make kernel dumps work with GEOM.phk2002-04-191-0/+5
| | | | | | | | | | 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. Sponsored by: DARPA & NAI Labs.

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.
