Recent mdadm versions introduced an interactive prompt when creating RAID arrays without an explicit bitmap configuration: "To optimize recovery speed, it is recommended to enable write-intent bitmap, do you want to enable it now? [y/N]?" This behavior was introduced by upstream change: https://github.com/md-raid-utilities/mdadm/commit/e97c4e18c847803016aa60066cb6e57c528d83a6 In non-interactive environments such as Anaconda, this prompt blocks installation and causes RAID creation to hang. Fix this by explicitly enabling the internal bitmap when creating RAID arrays.
