Some of these are obsolete and have been removed in newer kernels. NF_NAT ones have been superseded by / renamed to:
CONFIG_NF_NAT
CONFIG_IP_NF_NAT
CONFIG_IP6_NF_NAT
I'm not sure about CONFIG_INET_XFRM_MODE_TRANSPORT but I believe it's
now incorporated into other XFRM config variables in newer kernels. I
will need to look at the kernel changelogs. But you should be fine
without it.
AUFS is not part of the main kernel tree, so the following option does
not apply:
CONFIG_AUFS_FS
That said, Docker does _not_ require AUFS, but it does still support it
as an option. Docker docs, recommend using OverlayFS instead which is
also part of the main kernel tree.
As far as I recall there are patches and overlays that will allow you to
enable AUFS if needed. Debian, for example, does not include AUFS and
instead uses DKMS for AUFS support.
The CFQ I/O scheduler is obsolete and has been removed, so the following
do not exist and have no alternatives except for running an older kernel:
CONFIG_IOSCHED_CFQ
CONFIG_CFQ_GROUP_IOSCHED
Docker will run just fine with the BFQ scheduler.
Generally speaking the docker kernel validation script is fundamentally
flawed by design - it doesn't check the kernel options based on the
kernel version. Instead it uses as single global list of CONFIG options
and matches against that.
