Debian ported to G1
Over the weekend, a major G1 bug came to light. So what do you suppose happened when you typed Linux commands into any Android program under firmware 1.0 TC-RC29? According to Ed Burnette over at ZDNet, you executed them. Every keystroke was echoed to a root-authorized command shell. Typing telnetd started the telnet daemon. Typing reboot meant that, well, you needed to wait for a few seconds while your phone rebooted.
On the one hand, this was pretty hideously awful news for Google who went to work to push out a patched update. On the other, it was great news for the jailbreak crowd who used it to enable the telnet shell and sneak their way into the G1's innards. With that in mind, Jay "saurik" Freeman took the G1's shell to the next level. He got Debian Linux running on his G1 under RC29. Debian takes you past what Freeman calls "Google's overly simplistic busybox replacement, toolbox" and into real Unix-land.
