If running CentOS, check your grub.cfg as your VM may not boot otherwise

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.c… 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.
