It doesn't help the bootloader but /dev/FOO.ctl may be an option
for dumping configuration data into a device.

Passing binary blobs back and forth through sysctl requires code
in sysctl(8) to {en,de}code whereas the all-text approach makes
the OID tree look messy. It would be nice if sysctl grew a
configuration file (or maybe magic OIDs that let it retrieve
the description of opaque OIDs).
