Just switched my root-on-SSD home/var-on-HDD setup over to a single-partition dm-cache setup which automatically caches useful blocks... and it all works!
Hopefully, this will speed up Docker and Firefox going forward. 🥲
...I did feel like a wizard for having to write my own mkinitcpio hook 🎩 - thankfully I had https://wiki.tnonline.net/w/Blog/dm-cache:_Linux_Accelerated_Storage to guide me!
Would anyone be interested in a longer write-up on how I got all that working? 😇

On a random note, having something like fstab, but for devicemapper configurations, could be really nice—especially looking at the fact that Arch has separate mkinitcpio hooks for dmraid and dmcrypt already.
..Yeah, yeah, I know, I can just use LVM at that point.. but where's the fun in not baking things in the initramfs instead? 😂 😁
