Hi all

I have got mythbuntu to be a pxe server and can pxe to other computers on the network

but somthing i dont get is how it is able to remeber what iv done to each comp

for example I boot pxe mythbuntu on comp1 and install vlc
if I then reboot it, it still has it installed, without effecting comp2

my question is how does it remeber this?
it must be stored on the server, but where?

I suspect in the i386.img file, but how do I open/edit this
I wish to delete one comp and then reboot it (wich should effectivly reinstall it)
thanks

If you make changes on the client it'll alter the overlay for that machine, these can be found here

/var/cache/mythbuntu-diskless/overlay/${mac address}/

The image file is produced from /opt/ltsp/i386/ changes can be madeto all clients if you alter this inside a chroot and then rebuild the image see https://help.ubuntu.com/community/MythTV/Install/Hardy/Diskless

this is good to know. Say I mess up with a client, if I delete the overlay mac address directory and everything inside it will it then basically be fresh on the next boot of that client?
