Yes, although it's not particularly simple and will cause applications
that use libkvm to become quite confused. For example, if your /usr
filesystem is on wd0s1e, you can say
load disk0s1e:/src/sys/compile/MYKERN/kernel.debug
inside the loader (you may need to say 'unload' first to remove the
default kernel). This will leave the kern.bootfile sysctl saying
"/src/sys/compile/MYKERN/kernel.debug" and thus any application trying
to read the kernel symbol table will fail. You can hack around this by
placing a suitable symlink in /.
