Some of these are obsolete and have been removed in newer kernels. |
| 2 |
|
| 3 |
NF_NAT ones have been superseded by / renamed to: |
| 4 |
|
| 5 |
CONFIG_NF_NAT |
| 6 |
CONFIG_IP_NF_NAT |
| 7 |
CONFIG_IP6_NF_NAT |
| 8 |
|

I'm not sure about CONFIG_INET_XFRM_MODE_TRANSPORT but I believe it's |
| 10 |
now incorporated into other XFRM config variables in newer kernels. I |
| 11 |
will need to look at the kernel changelogs. But you should be fine |
| 12 |
without it. |
| 13 |

AUFS is not part of the main kernel tree, so the following option does |
| 15 |
not apply: |
| 16 |
|
| 17 |
CONFIG_AUFS_FS |
| 18 |
|
| 19 |
That said, Docker does _not_ require AUFS, but it does still support it |
| 20 |
as an option. Docker docs, recommend using OverlayFS instead which is |
| 21 |
also part of the main kernel tree. |
| 22 |
|
| 23 |
As far as I recall there are patches and overlays that will allow you to |
| 24 |
enable AUFS if needed. Debian, for example, does not include AUFS and |
| 25 |
instead uses DKMS for AUFS support. |
| 26 |
|
| 27 |
The CFQ I/O scheduler is obsolete and has been removed, so the following |
| 28 |
do not exist and have no alternatives except for running an older kernel: |
| 29 |
|
| 30 |
CONFIG_IOSCHED_CFQ |
| 31 |
CONFIG_CFQ_GROUP_IOSCHED |
| 32 |
|
| 33 |
Docker will run just fine with the BFQ scheduler. |
| 34 |
|
| 35 |
Generally speaking the docker kernel validation script is fundamentally |
| 36 |
flawed by design - it doesn't check the kernel options based on the |
| 37 |
kernel version. Instead it uses as single global list of CONFIG options |
| 38 |
and matches against that. |
