I've never once had a problem with nested mounts.  Is this a problem
people have?  First I've heard of it.

It would be nice if that were the case, however, in an automated
dual-boot system with EFI, we have to manage rEFInd *somewhere*, and
it is easier for us to manage it under configuration management in
Linux than in Windows.  Our managed dual-boot workstations need to be
able to reboot into the other OS during the evening for updates.
