Dell Wyse ThinLinux 1.0.3 Administrator’s Guide
ThinLinux RAW image upgrade
ThinLinux image is a tar ball of raw image, kernel and initrd. The raw image contains one ext4 read-write partition. The kernel and initrd is downloaded to existing system and used for image upgrade during next boot. ThinLinux can not be downgraded to SLETC11 SP3 using raw image. To upgrade SLETC11 SP3 to ThinLinux, use DELAYED_UPDATE method.
To upgrade ThinLinux using raw image, the image files should be on ftp or http server. The Server URL and upgrading options can be configured through INI and or admin GUI. The ThinLinux image supports Wyse 7020, Wyse 5020, Wyse 3030 LT, and Wyse 5060 platforms.
Raw image upgrade is done only through delayed update. Delayed update is a service started by network. It downloads the image and add-ons in background. Once it is ready, you will be prompted to restart the device. After the system is restarted, it is switched to upgrading mode, in which the hard drive is flashed with the new image. The device is restarted into new system after upgrading. The maximum size of the available storage is increased.
To upgrade from SLETC11, DELAYED_UPDATE add-on should be a newer version. Upgrading SLETC follows the above steps but the changes are not preserved when upgrading from SLETC SP3 to ThinLinux. Downgrading ThinLinux back to SLETC11 is not supported by raw image.
