Public bug reported:
On a 19.10 (pre-release, 20191016 daily) zfs installation, running 'os-
prober' (as 'update-grub' does by default) triggers the following error
message:
x@x:~$ sudo os-prober; echo $?
device-mapper: reload ioctl on osprober-linux-sda5 failed: Device or resource
busy
Command failed.
0
x@x:~$
The exit code is 0, so update-grub does not fail as a result.
