Hello all,
I've been thinking about creating a Gentoo USB stick for install and rescue
purposes (and, of course, just to see if I could). I've mostly followed the
Gentoo handbook (I used a single 4GB partition for the whole system, and no
swap). I've used genkernel for the kernel (so I can have a multi-system
capable kernel). I've gotten GRUB installed and working. My problem comes
in after what I believe is the init process:
Gentoo Linux; http://www.gentoo.org

fsck.ext2: No such file or directory while trying to open /dev/sda1
/dev/sda1:
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193<device>
* Filesystem couldn't be fixed :( [

Give root password for maintenance
(or type Control-D to continue):
If I give the root password, I can find no /dev/sda1. However, mount shows
/dev/sda1 on /, and there *is* a /sys/block/sda folders, with a sda1 folder
in that as well. It's almost like it had /dev/sda1, but then lost it
somehow.
Does anyone have any idea what's going on here? Any help would be
appreciated.
Have you seen http://www.sysresccd.org/Main_Page ? It's based on
Gentoo, you could check what they did to boot from a usb stick.

Excellent, thanks for that, I hadn't found it in my previous searches.
I'll have a look there.
