new swap system. The dump specification syntax is now more flexible,
and supports constructs like the following:
config netbsd root on ? type ? dumps on ?
- wildcarded root, fstype, and dump device
config netbsd root on ? type ffs dumps on sd0b
- wildcarded root, ffs root fs, always dump on sd0b
config netbsd root on de0 type nfs dumps on wd0b
- mount an nfs root using de0, and write kernel crash dumps
to wd0b
Also, garbage-collect some now unused code, now that swap configuration
is no longer handled by config(8).
