which OSs do you boot from USB, with no “trickery”? (Windows? OSX?
which Linux distros?)

so, don’t just accept the defaults…during the install from a live cd
you have full access to all packages and environments available (if
you are connected to the internet) on the DVD, or in all the various
Twas some kernel item that had to be changed in order for a computer to boot up to openSUSE on a USB stick.
I’ve used UNetbootin to install Fedora, Ubuntu, CentOS and other distributions. It handles making the USB bootable as well.
So what you are saying is that a LiveCD can also be used as a Netinstaller for openSUSE? I can, theoretically, during the installation choose Rythmbox and not Banshee, gNote instead of Tomboy, and include other apps like Komopzer, Cheese, etc. without having to first install the base system and then remove/add what I want?
I’ve gone through Netinstallers but those are a pain because everything has to come down the pipe. If I could do a Netinstall using a LiveCD, but the kernel, Yast, Gnome, etc. comes from the CD and everything “different” comes from the Net then that would be awesome!
First off, to validate that older versions of openSUSE did not work very well off USB Sticks without “trickery”
openSUSE 11.1 and earlier
Other than Ubuntu- and Fedora-type systems, the initrd on SUSE-type live CDs is not directly suitable for booting from a USB stick. The openSUSE system image creator, KIWI, can produce initrd files for Live USB media, however. These differ e.g., in the linuxrc script and in the supplied kernel modules.
Basically, to install the LiveCD ISO onto a USB Stick you type (and this can be done with any Linux system I am assuming)
“dd” is the command (disk duplicate?) which is more thurough than just copying because it includes bootup points and hidden pieces that copy misses. Most Linux, possibly Unix too, based systems include or can include the “dd” command*]the “if=” (input file) points to the ISO file downloaded*]the “of=” (output file) points to the location of the USB stick, which needs to be unmounted
*]“bs=4M;sync” is probably the block size and some other parameters I don’t know.
The page also goes into installing it via Windows, from a running openSUSE installation and adding a partition.
Instead of “install” a live-CD in your usb-stick, you could try a normal installation… I have a OpenSUSE 11.2 running on my 100G USB HD and it works faster than the Vista installed in the laptop’s hard drive (I know, I know, it is not very difficult :P)
The only “trick” is the Grub installation. Check that you are loading GRUB in th MBR of the USB disk, not in the MBR of the laptop’s hard drive…
Your method mades the USB stick the OS like any hard drive. I’m trying for a bootable install session where I can pick-and-choose which applications from everything located on the DVD.
The OS being on the USB stick is pretty fun though. I wish I could have gotten VMWare on my work laptop to boot from the USB so I could have my Linux installation running side-by-side with my work installation (without installing any non-official software ;)) Too late now anyway, I don’t have that VMWare on here anymore.
