Automating ports update with portmaster

[jaymax]

How can I automate ports update to keep it constantly current or 'near current'. I was thinking of running a cron job but was finally stymied by the realization of the need for considerable manual intervention

I am upgrading ports with portmaster and running in to frequent "Aborts" because of "IGNORE=" condtions in Makefiles or "IGNORE" in ports themselves. These are apparently associated with relocation of the base system of the respective port. These apparently neccesitates removal of the offending IGNORE= containing line in the Makefile and restarting.

Another issue is the need to manually set options in some upgrades.

Perhaps there is a non-interactive version around ?

How can one circumvent these.

Thanks
