bootstr

[Edgar Fuß <ef%math.uni-bonn.de@localhost>]

Simple question, but I can't find an answer documented:
Does the amd64 port support bootstr? I.e., can I temporarily boot another 
kernel by passing the name to reboot?
I know I can just redirect the /netbsd symlink or give the name to the 
secondary boot, but it would be more reassuring to know another reboot 
(on panic or whatever) would boot the normal kernel when testing a new one.
