I had a super fast but small SSD and didn’t know what to do with it, so I was playing with caching slow spinning LVM drives. It worked pretty good, but I got interrupted and came back a few weeks later to upgrade the OS. I forgot about the caching LVM, updated the packages in preparation for the OS upgrade, then rebooted. The LVM cache modules weren’t in the initfs image and it didn’t boot.
I should know better. I used to roll my own kernels since Slackware 1.0. I’ve had build initfs images for performance tweaks. Ugh!
Where’s my rescue disk?

Rescue disk 🤣 It’s hard enough to find a drive much less a disk.
Next time keep your old kernel around a while, you can always boot it to fix a goof instead of messing around with rescue images.
