Hints to write own seccomp filters
==================================

The different seccomp commands
------------------------------

Always have a look at 'man 1 firejail'.

 - seccomp
    Blocks all syscalls in the default-group.
     - The default-group is @default-nodebuggers, unless allow-debuggers is
       specified, then @default is used.
     - Listed syscalls and groups are also blocked.
     - Exceptions are possible by putting a ! in before the name of a syscall.
 - seccomp.block-secondary
    Allows only native syscalls, all syscalls for other architectures are blocked.
 - seccomp.drop
    Blocks all listed syscalls.
     - Exceptions are possible by putting a ! in before the name of a syscall.
 - seccomp.keep
    Allows only
