Public bug reported:
I had (I think, I can't quite remember) the filesystem.squashfs from a
live server ISO mounted when the kernel was updated. A menu entry for
this OS-resembling device is now in my grub.cfg:
menuentry 'Ubuntu 18.04.1 LTS (18.04) (on /dev/loop35p1)' --class ubuntu
--class gnu-linux --class gnu --class os $menuentry_id_option
'osprober-gnulinux-simple-cf05f674-791e-48eb-9b42-1bb903f4d024' {
insmod part_msdos
insmod ext2
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root
cf05f674-791e-48eb-9b42-1bb903f4d024
else
search --no-floppy --fs-uuid --set=root
cf05f674-791e-48eb-9b42-1bb903f4d024
fi
linux /boot/vmlinuz-4.15.0-29-generic
root=UUID=cf05f674-791e-48eb-9b42-1bb903f4d024 ro
initrd /boot/initrd.img-4.15.0-29-generic
}
I didn't select it :)
Something in this setup should be skipping loopback devices, surely?
