Hi I'm trying to understand why two of my machines will successfully boot FC5 from an external USB disk and one will not. initrd_usb.gz has been created right at the end of a clean FC5 install to a USB disk in "linux expert" mode. After removing the FC5 DVD Cont/Alt/F2 chroot /mnt/sysimage /sbin/mkinitrd --preload=ehci-hcd --preload=usb-storage \ --preload=scsi_mod --preload=sd_mod /boot/initrd_usb.gz \ 2.6.15-1.2054_FC5 This USB disk boots successfully on two machines with a bit of tweaking of grub interactively during the first boot and then changing grub.conf as required. gunzip -c initrd_usb.gz | cpio -i shows me the init file with "undocumented" commands such as mkblkdevs resume mkrootdev seems to have changed from man pages mount seems to have changed from man pages setuproot There appears to be no mkinitrd in core-source I can guess what some of the commands do but would like to know for sure. Advise as to where to find the details of the way nash now works would be great. Any other hints please Regards John
