The FreeBSD kernel expects to be loaded by /boot/loader and for it to provided a suitable environment. If one has chosen to not use /boot/loader (or include 'kenv' on their embedded boot media), they're already gone so far down the path of customization that hacking 'initrandom' should be expected. > I should note that I don't think the needs of embedded systems should > carry so much weight in this discussion that it leads to jumping through > major hoops. :-) > I think the most important point would be "Let failures be > soft ones" -- things you may think of as basic tools always available on > a minimal installation may not be there on a stripped down embedded > system; no big deal, just don't hang the system or anything else dire in > that case. I think that just adds to needless cruft in /etc/rc.d scripts that is hard to test and keep working -- as committers will 99.9999% time be in a full FreeBSD environment. I don't want to see every command in better_than_nothing() turn into "test -x ___ && ___". -- -- David (obrien@FreeBSD.org)
