Re: NetBSD on embedded devices

jm,
I have two of those units. Is that the “embedded system” you are going to install NetBSD on? If so you definitely do not need a “stripped down” version. I have one running my pfsense firewall and it hardly breaks a sweat. The other has had NetBSD, FreeBSD, OpenBSD and now DragonflyBSD installed on it. I have 8Gig of RAM and two hard drives installed. One thing I have to say, under FreeBSD it ran really hot. NetBSD 7.1 was installed with no problem and ran without incident for a good while and ran hot, but not where I needed mittens to handle it.
