Do you think it's feasible to *move* the name-based filtering

virt-v2v's do_fstrim to the libguestfs daemon's list-filesystems API

*ever* return these /dev/mapper/osprober-* nodes.
IOW all I'm proposing is that we move the same workaround deeper in the
stack.
Scratch that -- that still allows the grub2/osprober bug to spread too far.
Once we get some info from the rhboot team on the nature of this
grub2/osprober bug, can we perhaps unmount and "dmsetup remove" these
/dev/mapper/osprober-* block devices, in v2v, right after we call
"grub2_mkconfig_cmd"? That would contain this issue tightly.
