Neil,

Can you elaborate? For example how do you know a given *.iso* is grub
bootable? It there a test?  Is there a list? Just burn it to a usbstick
and test? Justuse a tool such as the aforementioned "isohybrid" can convert
any *.iso* to a grub bootable?  I like the idea of one image (iso) being
able to install via MBR or grub.  


How do you control the file system; set it up first on the target HDD/SDD?
Which tool do you use, as part of the usb package? gptfdisk (gdisk)?

Your telling me? So when did the gentoo liveDVD become "grub bootable" ?
Again, How do you know what a given images is capable, as the details of
so many seem to poor--> 2----> undocumented......?

Have you ever tried "pentoo-installer" off of a live gentoo dvd ?
with any usb iso?


curiously,
