I'm trying to learn a bit about the linux kernel keyring (as background for using ecryptfs). Does the kernel keyring store keys somewhere on disk, or does it get reinitiailized programmatically everytime the sytem is booted?
I've looked at the man pages and archlinux documentation on encryption but haven't found the answer. If there's other documentation on the kernel keyring, I'd like to know.
If the kernel keyring does store keys on the disk, where does it put the files?
