Hi,

great tutorial, helped me a lot! Hopefully this will end my SD card corruption problems. One thing I noticed is that there is a constant error in syslog: frequency file /var/lib/ntp/ntp.drift.TEMP: Read-only file system - ntp wants to write driftfile but is unable to. I fixed that so that driftfile command in /etc/ntp.conf points to /tmp/ntp.drift.

# /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help

driftfile /tmp/ntp.drift

Another thing - I added loggly integration so I'm able to debug my Pi after reboots when syslogs are gone. I kept rsyslog and followed this guide (besides Python specific logging it also adds adds syslogs).

Some info about driftfile: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/s1-Understanding_the_Drift_File.html
