Maybe we could also explain here how to get the old setting back. Like the "to stick to the old behavior ... set boot.kernel.sysctl..." sentence right below.

We already explain how to override values set in those snippets.
Listing each of those individually, with instructions on how to get to the old value would increase this paragraph quite a bit, and I'd like to keep it terse.
I think it's enough pointing at it, if someone stumbles over it, they'll likely look up the snippet file and think about what values to set anyways.

by looking at https://www.kernel.org/doc/html/latest/admin-guide/sysrq.html I could see the other sysrg functions which weren't enable sync command so I knew which one's were disabled.
