[Voyage-linux] periodic sync'ing from tmpfs to flash

[Teco Boot]

The daily build works without any update.
0.6.5 needed a fix (as far as I remember).

Once, I saw some old stuff in  syslog, it was about a week older 
then rotated syslog. That's why I want recordings of the recovery.

I tested on console, there I saw the copy_back and reboot.
But there is no trail of this. 

I a perfect world, the system starts, detects a need for recovery, 
copies back the temp folders, saves this activity in log files
and restart. I think only syslog matters.

Procedure would be:
 - save "syslog-start" (if needed)
 - copy back (the rsync part)
 - record recovery in syslog (e.g. with logger)
 - append "syslog-start" to syslog
 - reboot
I'll try something.

Thanks, Teco
