Red Hat Bugzilla – Bug 1360386
bond slaves of master which is slave of a bridge are sometimes not activated in installer
Last modified: 2017-08-01 05:17:07 EDT
When working on anaconda bug 1321288 we observe that sometimes bond slaves of master which is enslaved to a bridge are not activated in spite of NetworkManager configured with [connection] connection.autoconnect-slaves=1 in installer.

We only check for auto-connect circular dependencies here and thus a INFO level probably is enough. But I expect the activation to fail anyway later (AFAIU the kernel doesn't allow such configurations).
