Now the problem. I shut the full speed unit down for a few minutes to change locations and when I restarted it cgminer fails to start. The bone boots and I can tty into it. I can try to manually start cgminer and I get a "cgminer failed to start: Write Error".
(...)

I'm not able to find the string 'Write Error' (without caps as well) in cgminer source code.
Is it the exact error msg you get ?

The error seems to have been thrown by /etc/init.d/cgminer.sh
I can't seem to reproduce it right now. Instead I am getting "-sh: etc/init.d/cgminer: not found" however "less /etc/init.d/cgminer.sh" gives:

Code:

PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DAEMON=/usr/bin/cgminer
NAME=cgminer
DESC="Cgminer daemon"

set -e

test -x "$DAEMON" || exit 0

do_start() {

i2cset -y 2 0x71 2 $spi_ena

If so I guess your issue is located somewhere in the OS.
Anything useful in the log file ?

*Note: journalctl is the replacement for a "less /var/log/syslog"
http://www.freedesktop.org/software/systemd/man/journalctl.html

I have not gotten a result from journalctl. Probably because it is not in the path and I don't know where to find it.

I haven't messed with a Unix system for 30 years so I am a little rusty. :-) I would be more at home in JCL. I guess in the morning I will have to go find a good Linux book.
