Hello, The officially supported method to update a DFly system is building & installing from sources. However, it's hard or even impossible to build sources on a small VPS, and it's also not easy to transfer the built /usr/obj (which is rather big) to a remote VPS for an update.
So I wrote a simple shell tool to update a running DFly system using the pre-built releases or snapshots: https://github.com/liweitianux/dfly-update The basic update steps are: 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 I have tested updating one of my DFly vbox from 5.0.0 -> 5.0.2 -> 5.1 (master). The later update log is also put in the above repository as "example.log". Any tests, issue reports, and pull requests are very welcome! Thanks. Cheers, -- Aaron
