Hi,

I held off posting this to the "announce" list because I don't
understand the problem nor fully how to avoid/fix it, but another
CentOS-using customer has today ended up unbootable through not
getting the warning so I think I better had.

Have a read of this:

    https://mailman.bitfolk.com/mailman/hyperkitty/list/users@mailman.bitfolk.com/message/BJ5E24CX5ZX2ODBDJLVU44RTWMY4GP76/

Basically it seems at some point some CentOS update without notice
converts your grub.cfg to use "BLS" which is a thing that's Red Hat
specific and not available in upstream Grub. Since BitFolk uses
upstream Grub to boot your VMs, this leaves your VM unbootable.

There's info in that post on how to discover if this has been
enabled, and how to disable it, but it's unclear to me:

- what does it

- if it can actually be reverted once it's happened

So if you know more, please do let us know.

Cheers,
Andy
