You have been subscribed to a public bug by Eric Desrochers (slashd):

[Impact]

 * A recovery mode boot is effectively a normal boot on any system that
has ever had systemctl set-default run on it, i.e., the recovery kernel
parameter does nothing. In particular, ubiquity calls systemctl set-
default as part of the oem-config process, rendering recovery mode
useless on any oem-configured machine.

 * This is a regression from previous behavior, where recovery mode
would override a user-set default target.

 * This would also restore the intuitive behavior of this package. It is
intended to be run by setting a kernel parameter for a one-time boot,
and should therefore take priority over any other settings (such as
configuring a different default target).

[Test Case]

 * Run systemctl set-default multi-user.target

 * Use the GRUB menu to try to boot into recovery mode

 * Observe that you end up at a TTY, not in recovery mode

[Regression Potential]

 * Possible regression if someone set recovery as a default kernel
parameter, then relied on the default systemd target to override it.
This seems like an unlikely use-case.

[Original Description]

Fresh Ubuntu 18.04.2 server install

Try to boot to recovery mode from GRUB. Works correctly.

Use systemctl to set a different default, say systemctl set-default
multi-user.target

Try to boot to recovery mode from GRUB. End up at getty and not the
recovery menu.

Delete /etc/systemd/system/default.target* and recovery mode works
normally again.

I believe this can be fixed by changing normaldir to earlydir in the
generator.
