Yes. My point was only to remove potential errors for newer users running into this (easily resolvable) issue. > >> In terms of /etc/fstab, I think adding tmpfs to the kernel would be >> useful.

Been using md for years with Soekris/Alix boards. We're not talking about huge partitions here, so it shouldn't be an issue. I'm being more than generous here with space, but: /tmp -s30m /var/log -s15m /var/tmp -s5m I haven't done port building or any make on the BeagleBone, though. But it all seems fine with pfSense and their nanoBSD setup. I have only played around with tmpfs, but I'd imagine that in CURRENT it should be in good shape. > >> It might also make sense to add rc_debug="YES" and rc_info="YES" to >> the default /etc/rc.conf.
