ALPHA2 FINAL

Everything works perfectly and essential networking tools are installed. I'll be adding a swap file next which requires expanding the 2 GB root partition, so this is the final "text/console/base" image. I may not (probably won't) release a beta test image as there's really no point, other than for my own backup purposes. I'm running low on Google Drive space anyways.

At this point you really need to add a new user and install sudo. Once sudo is setup properly you can edit /etc/shadow to disable root. Just copy and paste the first line from another Ubuntu install. You're then ready to do things the Ubuntu way. ;)

NEWBIE COMMAND LINE QUICK START

I updated the apt cache this morning at Starbucks by:

ifconfig wlan0 up
iwlist wlan0 scan
iwconfig wlan0 essid "Google Starbucks"
dhclient wlan0
links google.com

I could then click the "accept terms" button and apt update.

Piping long output to more or grep is an essential skill:

iwlist wlan0 scan | more
iwlist wlan0 scan | grep ESSID


If you don't know what command to use ask your computer:

apropos dhcp

If you don't know how to use a command read the built-in manual:

man iwconfig

And when finished using your Pi3 end your session properly:

shutdown -h now

SYSTEM INFO

If you cat /proc/version you'll see I cross-compiled the AArch64 kernel on my AMD64 Gentoo machine. If you cat /proc/modules you'll see both spi and i2c are enabled, so you're ready to go with Pi makerspace projects. And if you cat /proc/cpuinfo you'll see all four CPU cores are enabled with hardware math (fp) and cyclical redundancy error checking (crc32) for data transfers.

It may only cost $35 but that's more power than most servers had just 20 years ago!
