More accurately, GRUB_DISABLE_RECOVERY only affects entries generated
by /etc/grub.d/10_linux . GNU/Linux entries from
/etc/grub.d/30_os-prober depend on output from linux-boot-prober,
which gets its information from many sources, though mostly from
existing bootloader configuration files. In other words, Debian's
entries for Ubuntu include recovery mode entries because Ubuntu's own
grub.cfg includes these entries. If you have
GRUB_DISABLE_RECOVERY=true in /etc/default/grub in Ubuntu, re-run
update-grub/grub-mkconfig in Ubuntu, then re-run
update-grub/grub-mkconfig in Debian, the recovery entries will go
away. I will update the documentation on GRUB_DISABLE_RECOVERY in the
grub manual to make this more clear.
