digitalocean-debian-to-arch

Not needed anymore since DO supports custom OS images now but I found this script quite interesting, setting up a "blockplan" and applying it from a minimal root FS in RAM to entirely replace a Debian OS with an ArchLinux install unattended and without rebooting (except as a very last step to actually boot into the Arch kernel using the replaced GRUB2) https://github.com/gh2o/digitalocean-debian-to-arch#how-it-w... I forked it to try and convert Debian installs from ext4 to btrfs. Unfortunately while it does work, that's a very bad idea since btrfs-convert produces a fs that fails to operate properly on the long run (IIRC there is - was? - some increasing random space usage that cannot be reclaimed, ever). https://github.com/lloeki/digitalocean-ext4-to-btrfs/blob/ma... BTW, the process to convert to btrfs is excellent, only creating btrfs

For those who want Arch Linux, you can just run this script: https://github.com/gh2o/digitalocean-debian-to-arch

There's a battle tested script that already does this specifically for DigitalOcean and can probably easily be adopted to other environments https://github.com/gh2o/digitalocean-debian-to-arch

Someone wrote a script to do just that: https://github.com/gh2o/digitalocean-debian-to-arch
