hmm, could be a bit spammy as warning, but we do not have a level between
info and warning task log; log_notice() could be nice to get sometimes to have
something that isn't as "alarming" as warnings, to avoid normalizing warnings,
which could drown out a more "real" one (not saying this isn't problematic at
all, but there may be some setups that test around with different boot/fw and
want to avoid dropping the efidisk in between).

What about ignoring the efidisk in the clone, and similar affected cases but
warn there instead, while keep the start message here as info log (until we got
a notice log level)?
