I'm ok with this id addition, but why can't Kata use keyctl to find the keyring by name? e.g. keyctl padd asymmetric "" %:.ipe < cert.der.
If the concern is that /proc/keys can be spoofed, that would mean other processes are already running while the keyring is still unsealed, which seems even less appropriate.
