Hi, I have tried the Gentoo LiveUSB guide http://www.gentoo.org/doc/en/liveusb.xml. When I boot from the usb stick, it apears that there is no device that can be mounted on /newroot. After hitting 'shell' at the command line I tried / # mount -t vfat /dev/sda1 /newroot. mount: Mounting /dev/sda1 on /newroot failed: Invalid Argument / # dmesg | tail ... Unable to load NLS charset cp437 FAT: codepage cp437 not found. The same kind of bug has been posted for the 2005.0 release and was fixed, but it appear that the bug has returned in the 2006.* releases. Reproducible: Always Steps to Reproduce:
This is likely because the codepages are enabled as modules, which works just fine for the CD. When genkernel creates the initramfs, it only copies the modules which are dependencies of modules listed in /usr/share/genkernel/<arch>/modules_load and the modules themselves, of course, into the initramfs. You can get around this by building your own kernel based on the CD kernel config. Just build fat32 and the "usual suspect" codepages (cp437, iso8859-1, utf8) into the kernel instead of as modules.
cp437, iso8859-1, and utf8 shoudl be built-in by default already if using the default config
Did you build your own kernel for the USB stick?
I did not build a custom kernel, but rather downloaded the 2006.1 minimal livecd for x86 and then followed the procedure http://www.gentoo.org/doc/en/liveusb.xml, which basically just explains how to transform a bootable CD into a bootable USB stick with minimal efforts.
Apparently, you didn't pay attention to the guide. "Warning: This guide is designed only to be used with Gentoo 2006.0. Do not attempt to use a 2006.1 CD or newer; you will end up with an unbootable USB disk." I'm marking this is invalid, since 2006.1 "out of the box" will not work with that guide.
