Dumbo - the dumb boot plugin

Do you have less flash-memory at your Dreambox for your daily Updates, Skins or Picons? Than Dumbo may be interesting for you. This plugin helps you to boot the Dreambox via a compressed image from a removable media like Compact Flash or USB-Stick. Dumbo is not a tool for Multiboot but it supports to boot via removable drives. Of course you can backup this kind of image. This plugin also helps to create a swap-file (/media/swap/swapfile) at a size of 200MB. Because of this you can use Dumbo at Dreamboxes with less RAM (like the DM 7025) without having problems due to less memory while decompressing or maintaining the image. The swap-file is activated during the boot process of Dumbo as told in the /etc/fstab. The Dumbo Plugin You configure Dumbo in this steps. Install the plugin into the flash image (the main image in the Dreambox). Than plug in the Compact Flash card or your prefered media to create partitions on it. You will get two partitions. The first to create a bootable FAT file system and the second to create the main ext3 file system. Now start the plugin Dumbo to choose the image that will be installed at your removable media. After about 5 minutes of decompression, installing and rebooting the Dreambox will be available for your new experiments. The complete configuration of the Dumbo-Plugin is described in this article.
