yes, /etc/ltsp/ltsp-update-kernels.conf is not created by default. in
it, you can include things like:

export BOOTPROMPT_OPTS="root=/dev/nfs ip=dhcp nfsroot=/opt/ltsp/i386"

this should then behave the way you would like- simply re-running
ltsp-update-kernels will then add whatever options you specify.


another option is to configure dhcp to point to a different pxelinux
menu, like so:

    filename "/pxelinux.0";

copy a pxelinux.0 to /var/lib/tftpboot/ , and configure
/var/lib/tftpboot/pxelinux.cfg/default however you want:

DEFAULT /ltsp/i386/vmlinuz ro initrd=/ltsp/i386/initrd.img root=/dev/nfs ip=dhcp nfsroot=/opt/ltsp/i386

this will also allow you to specify other boot menu entries, such as
allowing for a debian-installer netboot images or FAI or whatever you
want.


i would like to create more flexible menu generation in the future, and
briefly discussed it with other LTSP folks at the ubuntu developer
summit a few weeks ago:

downgraded the severity of this bug- hope some of these ideas work for
you.

thanks for reporting the issue. it's been on my mental TODO list for a
while now.

live well,
