[Firehol-support] Recommended method to re-resolve domain names

Apologies if this has been asked and answered before. The mailing list 
archives search function isn't working so I can't look for an answer there.

I'm using firehol 3.1.5 on Ubuntu 18.04. My configuration includes 
several domain names, some of which are dynamic DNS entries, so the 
underlying IP address may change from time to time. What is the 
recommended method for periodically re-resolving those domain names 
using firehol without disrupting current network activity?

In the past I've just added a "firehol start" to crontab. That works OK 
for resolving the names, but with Ubuntu 18.04 I suspect that method is 
disrupting existing traffic, especially long running rsync commands.
