I tend not to use LVM but I do pre-partition, pre-format and pre-label the disk BEFORE starting the install and the DO NOT format the disk during installation. (which deletes the labels !) The only real decisions are to do with how to boot. If the USB disk is to rely on the MBR of a main SATA/IDE type disk then choose the /dev/sdxy device associated with the USB disk at install time. Then add an entry to grub.conf on the fixed disk. title USB disk root (hdp,q) chainloader +1 In addition after install I would then configure grub on the MBR of the USB disk as well such that I can boot the disk with and without the presence of the "main", "fixed" disk. I did the whole of this on an external USB disk yesterday !!!! After first having learnt how to use jigdo to down load Fedora-Unity-20071218-8-i386-DVD.iso !!!!!!!! As stated by Mikkel I had to play with grub interactively to sort out the correct (hdx,y) !! John who wrote http://www.vigla.eclipse.co.uk/usb_install.pdf
