Comment 6 for bug 1085991

Both reuse & replace recipes use blkid, in my local experimentation I did managed to get blkid to hang on fat32 partition approximately similar to bug 987718 and bug 1044111.

But that got me thinking - both recipes are trying to detect existing ubuntu installations which should not be on a fat32/ntfs/hfs/swap partitions, so I want to skip mounting those & skip using blkid.
