Long story short. I screwed up badly and managed to run blkdiscard on my root drive instead of the intended disk. Am I completely screwed?

If you followed best practice, the only thing of value you have lost is /etc. Since /home, /var and friends are on different partitions, the easiest way to fix is to reinstall and restore /etcfrom backup - this will also link in the existing file systems via fstab.

I do have backups. /var, /home were on different partitions but on the same drive so restoring will take ages, I was hoping to avoid that. Ah well, lesson learned.. Thanks for the quick reply!
