can sbo break a multilib install?
 

Started from scratch with a fresh slackware64 install. First time I've tried to set up a multilib slackware and I'm using sbopkg to reinstall everything that I use from sbo. Just wanted to make sure that sbopkg won't try to grab packages from the official mirrors or anything and replace my multilib packages like slackpkg could do.
And if it can, how do I blacklist them in sbopkg?

As I understand it, sbopkg only pulls stuff from slackbuilds.org and will not pull packages from the Slackware distribution mirrors. Therefore, you need not worry about damaging your multilib system.

No, sbopkg is for Slackbuilds.org. Your multilib is safe using sbopkg.

great thanks both of you
