On install of the VyOS image with efi raid there were errors getting the uuid and
/dev/null messages in screen (due to calling dmidecode)

In some cases if on boot there can be some warning messages:

mount: mounting /dev/sda1 on /live/persistence/ failed: No such device
mount: mounting /dev/sda on /live/persistence/ failed: No such device
rmdir: '/live/persistence/': Device or resource busy
mount: mounting /dev/sdb1 on /live/persistence/ failed: No such device
rmdir: '/live/persistence/': Device or resource busy
