Configure cronlog file cleanup settings during install of VIOS

By default the /var/adm/cron/log file does not get periodically cleaned up.  This has caused us problems in the past, with /var becoming full preventing logins from occurring because the login files under /var cannot be updated with the login event.  The only way we have resolved/fixed the VIOS server is to reinstall it from scratch - not so bad in a 3 VIOS configuration, but not so good with only 2 VIOS servers on the Power frame.  When we install VIOS, we now update the /etc/cronlog.conf file with the following settings so that the cron log file no longer fills up /var:

logfile=/var/adm/cron/log

size=5m

rotate=4

compress

I then have to do a "kill -HUP pid_of_crond" to get the active cron process to reread (HUP = HangUP) the configuration file, and perform the cleanup automatically.

It would be great if these settings, or something like them, were in place as a part of the install image for VIOS.  It isn't often that we log into VIOS directly to see that /var is getting full.  I also don't always remember to set this up just as soon as a new Power server is setup with VIOS either, and it would be nice to not have to remember to do this.

Thank you,

Dan Bacus
