Title:
desktop/live cd netboot won't boot X
Status in “network-manager” package in Ubuntu:
Incomplete
Bug description:
using https://wiki.ubuntu.com/LiveCDNetboot
I am somewhat able to boot the desktop live cd over pxe, but it never gets
into
X or a prompt. but... if i boot into single, drop to a root propt, then run
startx, it boots into X, and then hangs.
This happens on 4 different boxes, including qemu, all of which run intrepid
just fine.
When I do it in qemu, after a min or 2 of blank display, it goes back to text
mode and I see:
m Starting bluetooth [ OK ]
Starting Network connection manager daemon: NetworkManager.

The 6 lines then repeat every 120 seconds.
Steps to repo this problem:
cd /var/lib/tftpboot/ubuntu/intrepid/
wget -N http://cdimage.ubuntu.com/daily-live/current/intrepid-desktop-i386.iso
mount
/var/lib/tftpboot/ubuntu/intrepid/intrepid-desktop-i386.iso on
/var/lib/tftpboot/ubuntu/intrepid/desktop type iso9660 (rw,loop=/dev/loop2)
# /etc/exports
/var/lib/tftpboot/ubuntu/intrepid/desktop
192.168.1.0/255.255.255.0(async,no_root_squash,no_subtree_check,ro)
# /var/lib/tftpboot/pxelinux.cfg/default
label ubuntu-intrepid-livecd
kernel ubuntu/intrepid/desktop/casper/vmlinuz
append initrd=ubuntu/intrepid/desktop/casper/initrd.gz boot=casper

The details of my qemu setup: https://wiki.ubuntu.com/QemuPxe
You can see the behavior in qemu without having to setup the pxe environment
by
just loading the casper kernel into qemu:
carl@dell29:~/temp$ sudo qemu -m 400 -net tap -net nic,model=pcnet hdb.qcow2
-kernel /mnt/nfs/shaz/intrepid/casper/vmlinuz \
-initrd /mnt/nfs/shaz/intrepid/casper/initrd.gz \
-append "boot=casper netboot=nfs
nfsroot=192.168.1.7:/var/lib/tftpboot/ubuntu/intrepid/desktop/ root=/dev/nfs
single -- "
and as a control, this works fine:
$ qemu hda.qcow2 -cdrom intrepid-desktop-i386.iso -boot d
