Updating netboot image Camsexchat zufallig

This works better if you have full powered PC's to work with, and are working with a large number of clients that would require too much CPU and RAM to run all their applications on one server.

Most of the examples there can be used for stateful nodes too.) Note: as an alternative to using genimage to create the stateless image, you can also capture an image from a running node and create a stateless image out of it. devpts /dev/pts devpts gid=5,mode=620 0 0 tmpfs /dev/shm tmpfs defaults 0 0 proc /proc proc defaults 0 0 sysfs /sys sysfs defaults 0 0 tmpfs /tmp tmpfs defaults,size=10m 0 2 tmpfs /var/tmp tmpfs defaults,size=10m 0 2 compute_x86_64 / tmpfs rw 0 1 cd /install/netboot/fedora9/x86_64/compute/rootimg/etc cp fstab fstab.

ORIG vi fstab proc /proc proc rw 0 0 sysfs /sys sysfs rw 0 0 devpts /dev/pts devpts rw,gid=5,mode=620 0 0 #tmpfs /dev/shm tmpfs rw 0 0 compute_x86_64 / tmpfs rw 0 1 none /tmp tmpfs defaults,size=10m 0 2 none /var/tmp tmpfs defaults,size=10m 0 2 _Note: adding /tmp and /var/tmp to /etc/fstab is optional, most installations can simply use /.

You can now change/fill in any osimage attributes that you want.

A general convention is that if you are modifying one of the default files that an osimage attribute points to, copy it into /install/custom and have your osimage point to it there.

It was documented her to show that you can restrict the size of filesystems, if you need to.

The indicated values are just and example, and you may need much bigger filessystems, if running applications like Open MPI.

When you finish the from part 5 onward of the above instructions you should have a booting machine in the same state as you would had you followed them from part 1 onwards.

- Remember that it will not work if creating symlink out of chroot.

Create a symlink called 'vmlinuz' what points to your current kernel version in that same directory.

Create another symlink called 'initrd.img' that points to the that your are currently using (same version as your kernel).

Create one more symlink called 'config' that points to the config your using.
