However, it's time-consuming, hard or even +impossible to build sources on a small or low-end VPS, and it's also not +easy to transfer the built "/usr/obj" (which is rather big) to a remote +VPS for an update. + +Therefore, a smiple tool to update a DragonFly BSD system directly from +the officially built release or snapshot images is very useful and +necessary. + +This tool refers to the installation procedures and the official source +upgrade processes to implement the update task, which mainly includes +the following steps: + +1. check local and remote available versions; +2. download the latest release/master system image (.img.bz2); +3. decompress and mount the image; +4. backup the current kernel and world (including /etc); +5. install the kernel and world using cpdup (similar to the installer); +6. identify the new/changed /etc files, rename the conflicting ones with + suffix ".__new__" and then copy over; +7. get obsolete files from Makefile_upgrade.inc and remove them; +8. umount, remove image file, show the "*.__new__" files need manual + merge.
