[gentoo-user] Can we please get a USB-stick install boot image?

[gentoo-user] Can we please get a USB-stick install boot image?

[waltdnes]

  I don't know if this is the proper list to post this request to.  I've
been using linux for a dozen years, and am capable of reading and
following instructions.  But, after a lot of dicking around, I still
haven't been able to modify a CD boot image get Gentoo to boot from a
USB stick.  For my netbook (look ma, no CD) I ended up booting Knoppix
from a USB-stick, and installing Gentoo from there.

  There are quite a few machines without CD drives being sold today, but
none that I'm aware of that won't boot from a USB stick.  I believe that
USB-stick images, rather than CD images, should be the default
distributed boot images on the mirrors.  And think of all the CD's that
won't end up in the landfill, after an install image is used once.

use UNetbootin (http://unetbootin.sf.net) to create a bootable USB stick.

The problem is what size do you make the image, not all USB sticks are
equal. A simpler option is to use Unetbootin to convert the ISO onto a
USB stick.

Incidentally, you could try dd'ing the ISO to a USB stick, this works
more often that you might imagine.

While I'd also like to see USB boot media, I'd like to observe that
SystemRescueCD, which is based on Gentoo, is perfectly good to use as
an install medium.

here's one I prepared earlier ;)

This is from 2008:

and these are some notes of mine on syslinux which may help a bit too:

I have done that. Here's basically what I did.

#!/bin/sh

ISO=/home/ftp/pub/install/install-amd64-minimal-20081213.iso

mkdosfs -F 32 /dev/sdc1
dd if=/usr/share/syslinux/mbr.bin of=/dev/sdc || exit
mount -o loop,ro -t iso9660 $ISO /mnt/iso || exit
mount -t vfat /dev/sdc1 /mnt/media1 || exit
cp -r /mnt/iso/* /mnt/media1 || exit
sync
mv /mnt/media1/isolinux/* /mnt/media1
mv /mnt/media1/isolinux.cfg /mnt/media1/syslinux.cfg
rm -rf /mnt/media1/isolinux*
mv /mnt/media1/memtest86 /mnt/media1/memtest

umount /mnt/iso
#vim /mnt/media1/syslinux.cfg 
sed -i -e "s:cdroot:cdroot slowusb:" \
     -e "s:kernel memtest86:kernel memtest:" /mnt/media1/syslinux.cfg

umount /mnt/media1
syslinux /dev/sdc1

try the manual from the systemrescuecd (a very recent gentoo based livecd)
