Hi, Jim:
"rootdelay=x" is neccessary for installing moblin images to usb disk, while
the modifications to correct device name in grub.conf and fstab are done for
USB device name changing issue. Anyway, it depends on your real system, then
you may not need to modify it. :)
For fsck failure, it has been fixed in latest image by adding more /dev
nodes, sda1-10, sdb1-4 in /etc/udev/makedev.d/00-base.files to pre-create these
nodes at the beginning.
For intermittent boot hang, I haven't met it before, you can report a bug
to http://bugzilla.moblin.org for tracking.
tcpdump/wireshark packages are not in Moblin repo now. You can build and
package it on moblin image for your usage.
Thanks.

You should boot from the initial usb with moblin live image and run
"Boot and install" grub option to start the install.
After you installed the moblin to another usb stick successfully, you
can mount the partitions of that USB disk
#mount /dev/sdx2 /mnt/sysimage
#mount /dev/sdx1 /mnt/sysimage/boot"
And then modify the grub.conf ( /mnt/sysimage/boot/grub.conf) and fstab
(/mnt/sysimage/etc/fstab) for the installed image on your usb disk.
For grub.conf, add "rootdelay=8" and modify "root=/dev/sdx" to the
correct device name in kernel command line
For fstab, make sure it use the correct device name.
Hi all. I'm new to the list, but I just wanted to say that "rootdelay=8" worked
for me. I was able to boot a MSI Wind U100 from a SD flash (root=/dev/sdb1).
Thanks!
I also wanted to report a couple problems with moblin (alpha2). The first time
I installed moblin was on a partition on my internal hard drive. I had to
temporarily hijack my Fedora swap partition (sda6) in order to install moblin.
The first problem I encountered was during boot. It would report an error when
it tried to run fsck.
Welcome to Moblin
fsck.ext3: No such file or directory while trying to open /dev/sda6
/dev/sda6:
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>
[FAILED]
*** An error occured during the file system check.
*** Dropping you to a shell; the system will reboot
*** when you leave the shell.
Give root password for maintenance
(or type Control-D to continue):
Upon closer inspection, it appears to be a race condition. I imagine there
would be all kinds of issues when trying to drastically cut down the boot time.
I believe fsck ran before /dev/sda6 node was created. I added a "sleep 1"
before the fsck call in /etc/rc.sysinit which seemed to fix my problem. This
probably isn't the proper fix, but it was an acceptable workaround for me.
The other problem I encountered is an intermittent boot hang. Here are the last
few lines of the console log before the hang occurs:
[ 3.231080] Bluetooth: HIDP (Human Interface Emulation) ver 1.2

Overall, I'm very impressed with this distro and is becoming my distro of
choice. WPA wireless functioning and power management/suspend works instantly.
Wake up/resume happens in a flash and I can access the network instantly. It
makes for a wonderful user experience.
Would love to see networking utilities such as tcpdump/wireshark. Are there
plans on adding this? Congrats on your great progress. Thanks.
