If the “transaction” for default.target fails, will systemd try to boot to emergency.target?
If a unit A that conflicts with a unit B is scheduled to be started at the same time as B, the transaction will either fail (in case both are required part of the transaction) or be modified to be fixed (in case one or both jobs are not a required part of the transaction).
-- man systemd.unit
If we hit this failure case when systemd tries to reach default.target during boot, does systemd try to fall back to emergency.target?

No.
It will fallback to rescue.target [1] instead, which is hardcoded in systemd [2].
And, if that fails too, systemd will quit [3][4].

Thanks for finding the right function. I think the failure I mentioned will actually not failmanager_load_startable_unit_or_warn(), it will fail atmanager_add_job(), so there is no fallback andsystemdwill just quit.
