In the process of building an amd64 diskless box, I am trying to make a bootable USB key with no success up to now.
The first problem I encountered was related to ext2/vfat. I initially tried to format the key as ext2, but grub refuses to install on it. Even though I copied the /boot/grub/* directory into the key, and I see it is there, grub does not see it. The problem does not happen with vfat. So I worked around that and created two partitions in the key, a small vfat for the /boot and a 2Gb ext2 for the /. I copied the stage3 into the / with no problem. In the /boot I put the kernel image which I am already using on the same box, for now with discs still connected. All the modules are compiled in. When I boot from the key, grub enters the shell (although I did create the grub.conf and menu.1st, so I don't understand why it doesn't show the menu). I manually specify the kernel file location and root parameter: > kernel /linux-2.6.24-gentoo-r4 root=/dev/sdg1 > boot The kernel starts to load, but panics because it is unable to find the root partition. When it stops it shows the available partitions, these include all the hard disk partitions but no USB key partition. In fact, if I omit the 'root' parameter from the grub shell the boot works fine but it uses the hard disk root partition instead of the USB one. >From the log on the screen the USB controller seems correctly detected, so I don't understand why it is not finding the root. While writing this one idea comes to my mind, maybe it is failing because I attach the key to a SDC/MMC/USB card reader? This evening I'll try to plug it into a different USB slot. Any other ideas welcome. raffaele -- gentoo-amd64@lists.gentoo.org mailing list
