+smartos-platform-upgrade
+========================
+
+A script to simplify upgrades of USB booted SmartOS installations.
+
+Installation
+------------
+
+Drop the script in `/opt/local/bin` on the GZ.
+
+Usage
+-----
+
+Run the script. It'll find the USB stick, download the latest platform from
+Joyent, do the upgrade and report its status. The download and update platform
+stages will probably take a few minutes each.
+
+```
+[root@00-25-90-7d-03-8b ~]# platform-upgrade
+Checking current boot device... detected /dev/dsk/c0t0d0p1, mounted, OK
+Downloading latest platform... OK
+Verifying checksum... OK
+Extracting platform... OK
+Updating platform on boot device... OK
+Activating new platform on boot device... OK
+
+Boot device upgraded. To do:
+
+ 1) Sanity check the contents of /tmp/tmp.KCaawL/usb
+ 2) umount /dev/dsk/c0t0d0p1
+ 3) reboot
+[root@00-25-90-7d-03-8b ~]# 
+```
+
+Once the upgrade is done, verify that the contents of the USB stick looks sane,
+unmount it and reboot to the new platform.
+
+```
+[root@00-25-90-7d-03-8b ~]# ls -l /tmp/tmp.KCaawL/usb
+total 24
+drwxrwxrwx   1 root     root        4096 Jan  3  2011 boot
+drwxrwxrwx   1 root     root        4096 Dec 28 16:03 platform
+drwxrwxrwx   1 root     root        4096 Dec 28 15:24 platform.old
+[root@00-25-90-7d-03-8b ~]# ls -l /tmp/tmp.KCaawL/usb/platform
+total 9

+[root@00-25-90-7d-03-8b ~]# umount /dev/dsk/c0t0d0p1
+[root@00-25-90-7d-03-8b ~]# reboot
+```
+
+By default, the first removable device found is assumed to be the boot USB
+stick. If this is not the case, the correct device name can be given on the
+command line:
+
+```
+[root@00-25-90-38-94-04 ~]# platform-upgrade /dev/dsk/c1t0d0p1
+Checking current boot device... using /dev/dsk/c1t0d0p1, mounted, OK
+Downloading latest platform...
+```
