hey there, i had got the same issue as op however luckily, after hours and hours experimenting… i finally got my arch up and running now.

for some reason after upgrading the system, the systemd just can’t mount the /dev/vda1 correctly with write access.

so what i did is a bit hacky:

  1. shutdown your droplet
  2. boot from recovery iso, you can select this from recovery menu
  3. start your droplet and open console
  4. select 1 from menu to mount the disk
  5. select 5 to chroot into your arch
  6. move original /sbin/init, rename it as init.real: mv /sbin/init /sbin/init.real
  7. create your own “init” to mount the disk correctly, don’t forget to chmod +x it, here is the script:

mount -o remount,rw /dev/vda1 /
exec init.real

at last shutdown your droplet and turn of recovery mode, and reboot it

Arch Linux is not supported by DigitalOcean as a droplet distribution anymore. I doubt you’ll get much help with this.

If you’re using “DigitalOcean Debian to Arch” on the droplet then ask for advice through the issues page perhaps.
