Hi Radek,

My intend is to install Fedora on an iSCSI target using iSCSI only,
without using a physical attached DVD/USB stick.

As far as I've found out it's only possible to have one device in iBFT.
That's why I'm using a small filesystem for LiveOS on the same iSCSI target
so that the remainder of the iSCSI target (30GB) can be used for installing
Fedora.

When Fedora is installed the small partition used for live could be
removed (or re-used for reinstalling Fedora).

I didn't try to supply the Fedora-Workstation-Live (iso) from another
iscsi target, that might work! I'll try that and report back.

Thanks,
Dick Marinus
