In this Slack thread, Adrian let us know about a conversation where a customer's build pipeline was having problems that turned out to be due to a mismatch in the glibc packages being used across packages to be installed. The basic solution is to pin packages to make sure things match rather than allowing packages that are too new (built on a newer version of glibc) to be selected for install/use. There are more details in the Slack thread.
Adrian: "I'm thinking apk add debugging and check what we say in our getting started tutorials to make sure it includes stuff on how to avoid mismatched packages."
I think this sounds like a good idea and we should try to get it scheduled.
