    SubjectRe: [PATCH] Capabilities, this time in elf section
    Least astonishment in this case would mean that the binary has the
    capabilities available to its EUID. In the case of a SUID binary
    the EUID is the UID of the owner of the binary.

    This is the reason for SUID binaries.

    Non-SUID binaries get their EUID from the UID of the user
    running the binary. So they can only have capabilities that
    are available to that user.

    If a binary requires a capability to run to do its job
    then it either needs to be run by a user that has that
    capability or it needs to be SUID to a user that does.

    SUID binaries should _still_ be rare, but since they
    will not all be SUID-root the potential security
    risk will be reduced.
