This past week, I had the need to install opensolaris on a host using a USB thumb drive. To create a bootable USB drive, I first needed to snag the distribution constructor tools via mercurial (I ran these commands from an OpenSolaris host):
pkg install SUNWmercurial
hg clone ssh://firstname.lastname@example.org/hg/caiman/slim_source
The caiman slim source Mercurial repository contains a script named usbcopy, which you can use to copy a USB image from the genunix site to your USB drive:
Found the following USB devices: 0: /dev/rdsk/c9t0d0p0 7.6 GB Patriot Memory PMAP Enter the number of your choice: 0 WARNING: All data on your USB storage will be lost. Are you sure you want to install to Patriot Memory PMAP, 7600 MB at /dev/rdsk/c9t0d0p0 ? (y/n) y Copying and verifying image to USB device Finished 824 MB in 336 seconds (2.4MB/s) 0 block(s) re-written due to verification failure Installing grub to USB device /dev/rdsk/c9t0d0s0 Completed copy to USB
After the image was copied, I plugged the drive into my machine and it booted to the opensolaris desktop without issue. From there I did an install and everything appears to be working flawlessly! Nice.
