Re: [libvirt] [PATCH 3/3] storage: Resolve issues with disk partition build/start checks

https://bugzilla.redhat.com/show_bug.cgi?id=1439132 Fix some issues discovered when building between multiple different supported disk partition types. 1. The "dvh" and "pc98" were specifically checked during the blkid partition processing in commit id 'a48c674fb', but commit id 'a4cb4a74f' really messed things up by missing an else condition causing PARTEDFindLabel to always return DIFFERENT. 2. Add the "bsd" to the list of format types to not checked during blkid processing even though it supposedly knows the format - for some (now unknown) reason it's returning partiion not found. So let's just let PARTED handle that too. 3. During 'matrix' testing of all possible combinations I found that if device is formated with "gpt" first, then an attempt is made to format using "mac", a startup will fail. By adding a clearing of the first 2048 bytes of the device (similar to the logical pool code), the issue is resolved.
