How would you do a "firmware" upgrade on a running NetBSD system ?
Any ideas how it can be done ?
Would it be possible to just upload new kernel image to a rw mounted file system and overwrite existing one mounting the root fs rw ?
How do NetBSD folks do things like that ?

I am intenting to write a HowTo/Guide for the generations to come.
