but grub.cfg fails to include boot records for /dev/sda6, /dev/sda7, /dev/sda8.

Examining the log records generated by linux-boot-prober revealed that:

  linux-boot-prober /dev/sda6

reported:

  Sep 7 21:01:18 elf11 linux-boot-prober: Device '' does not exist; skipping

I changed

  newns

to

  newns "$@"

which results in the device argument being passed correctly and the correct records being generated in grub.cfg.
