Raspberry Pi Jessie has Broken Cron/at Mostly Solved

2017-09-19 Thread Martin McCormick
Cron was working all along but I fooled myself.  The true problem
right now is that all the job output such as error messages or
anything else that becomes either standard error or standard
output is presently vaporizing somewhere rather than being mailed
back to me. I also thought I remembered seeing a message from
cron every minute in syslog but that only happens when some job
matches the time criteria. Since the Pi has only one working line
in crontab, there isn't much to see most of the time related to
cron.  

It also looks like cron as configured on this Pi doesn't
default to off and the kodi issue was a red haring. The real
issue is the cronjob output going "poof!" As soon as I figure
that out, trouble-shooting will be normal.

/etc/default/cron on the Pi is identical to
/etc/default/cron on a Debian wheezy system. It's nice to know
the Pi is not setup too differently.

Anyway, thanks for helping me think on this.

Somebody is assuming that the only use for a Pi is to run a home theater
and that users can't handle the terrifying task of carrying out a
trivial edit of a text file.  You probably just need to edit
/etc/default/cron.

If the Pi is not powered up all the time install anacron.

I've no idea, but the obvious question is: is this because 'Jessie lite' 
clearly doesn't have all the features of a full OS?

Raspberry Pi Jessie has Broken Cron/at

2017-09-19 Thread Martin McCormick
This raspberry Pi is running jessie lite.  Raspberry Pi
documentation says that cron and at jobs are disabled by
default. There is a very odd fix recommended by some
documentation in which one edits a file named

/home/pi/.kodi/userdata/addon_data/script.raspbmc.settings/settings.xml

You supposedly edit that file and change a variable which allows
cron and at jobs to now run. Since unix-like systems have had
running crons for decades, is there a more conventional way to
restore this functionality?  There is something odd about needing
kodi installed to make cron work.  Kodi is not installed which is
why I am asking before wasting all this disk space just to turn
cron on. If you don't need kodi, could you just create that path
and file with that one variable to act as a place-holder and
enable cron?

Thanks for all constructive ideas.
