If you want to keep up to date on the latest with Ubuntu, you can install zsync (its in the Ubuntu repositories) and use it to keep the developmental CD images up to date. The daily builds are accompanied by zsync configuration files that help locate those blocks in your image file that need to be changed to keep up with the online images. That allows downloading only what has changed. The zsync commands for the desktop versions of Natty are
zsync http://cdimage.ubuntu.com/daily-live/current/natty-desktop-amd64.iso.zsync
zsync http://cdimage.ubuntu.com/daily-live/current/natty-desktop-i386.iso.zsync
I’ve got these images on the USB stick I set up for multiple boot (see multiple boot from ISO on USB pen drive) so I can update the image and then easily reboot to see how it works and what it does. The grub.cfg stanzas for this are
menuentry "Ubuntu 11.04 Natty 64" {
loopback loop /natty-desktop-amd64.iso
linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/natty-desktop-amd64.iso noeject noprompt splash --
initrd (loop)/casper/initrd.lz
}
menuentry "Ubuntu 11.04 Natty 32" {
loopback loop /natty-desktop-i386.iso
linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/natty-desktop-i386.iso noeject noprompt splash --
initrd (loop)/casper/initrd.lz
}
menuentry "Ubuntu 10.10 Desktop ISO" {
loopback loop /ubuntu.iso
linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/ubuntu.iso noeject noprompt splash --
initrd (loop)/casper/initrd.lz
}
Natty is heading towards the Unity desktop which will take some getting used to. The last ‘alpha’ I tried had problems with pull down menues that didn’t pull down. Being able to test these builds of Natty not only can help the developers with testing feedback but also gives me some time to figure out how things work and what is needed to adapt from the Gnome Desktop.
