- also, use good known USB cable. Initially I tried micro USB cable that did not work, possibly was good just for charging.
- good USB cable will make
/dev/ttyUSB0 appear on Linux right after connecting
- type the
stty com0 115200 and set tty com0 commands by hand rather than pasting them. When pasting they will usually end up corrupted and the system
will either stop writing to console as a result (e.g. 115200 will be missing the last zero) or the system will reset to BIOS after loading the kernel
- GPT does not work, one has to use MBR
- use
disk install, installXY.img contains all the sets, no need for the network during the install
- deselect Xorg and games (
-x*, -games*)
/etc/hostname.* interface description is limited in length (to 64 chars)
SIOCSIFDESCR / IFDESCRSIZE = 64
- leave the swap for
savecore (cannot really be disabled it seems, at least not with =NO in /etc/rc.conf.local)
- there does not seem to be vanity network interface naming, so all parent interfaces in
hostname.vlan* have to be rewired when changing the driver of the physical network device
- do not forget to add the
/etc/fstab entry for MFS /tmp: swap /tmp mfs rw,noatime,nodev,nosuid,-s=327680 0 0
