I didn't want to hijack the "Problem updating to Buster" thread, but it follows on from:

(The origin of my system will differ slightly in being debootstrap from another partition running jessie, rather than an upgrade of an older system.) At step 3 (where I'm installing all the packages I want on the new system) remove grub if it's there. (IOW I wouldn't deliberately be installing it. I see no dependencies.) Step 4 as above. Step 5: Now I'm back running jessie (whence I executed the debootstrap and so on). # grub-mkconfig > /boot/grub/grub.cfg which will os-prober the new grub-less system and add entries for it under ### BEGIN /etc/grub.d/30_os-prober ### Step 6: # grub-set-default 'Debian 9 (on /dev/sda7)>osprober-gnulinux-simple-swan07' using the strings I find there. # reboot Would this work, and reboot into the grub-less system? Any snags or gotchas? Cheers, David.
