Comment # 9 on bug 1230002 from Cresce

I used the -DVD one, and I am sure that I could choose systemd-boot offline.
Being some kind an offline installer, with the chance to use systemd-boot with
just two clicks away and with no particular tinkering, I would still expect to
work. I've just tried the newest snapshot too and seems that it stays the way I
found the earlier one.

Anyways, good to know that it might not be a bug but a simple decision to make.
After all, the installer blocks the user before it formats/deletes/creates
partitions and/or lose data.
