Remove KEYRING from kernel! Re: KEYRING:persistent and ssh

[Cedric Blancher]

Depends what you call "nice". KEYRING is a gaping security hole in
case of Docker or chrooted apps because it "leaks" keys through the
isolation AND does this randomly even into other Docker instances.

IMO the whole KEYRING stuff should be removed from the Linux kernel
and replaced with a sane design.
