[Kernel-packages] [Bug 1557994] Re: s390/kconfig: setting for CONFIG...9P....

[dann frazier]

=m means they are build as dynamically loadable modules. As a general
purpose distribution, we default to building things as modules when
possible. This means that the code is only active and consuming memory
when it is being used. =y would mean that the code is always loaded -
consuming memory, and increasing the attack surface area for security
issues, even if the user never needs that code.

@Tim,

Imho 9P can/should be =y on all arches, cause then one can use 9P as
root/boot device. And it opens the interesting posibility of e.g.
"booting" an lxd container in kvm, and the like.
