Looking at the help for the "second extended fs support" option under File Systems, you are told that unless you intend to run under a DOS partition you will need to enable this. I have been informed (being new to Gentoo) that in fact you only need it for ext2 support. The Help doc should be updated to reflect this. Obviously, were it required by all the other file systems, or for Gentoo to run, they should all be listed under ext2 in the tree structure, with their options disappearing when ext2 does.
I'm logging it as minor rather than trivial as it does affect function rather than just the cosmetics of the system.
Steps to Reproduce:
ext2 is required afaik. The kernel help is correct and I don't think we tell the user otherwise elsewhere...
*** Bug 56043 has been marked as a duplicate of this bug. ***
Well, ext2 is not required for operation. It *used* to be, before there were other full-featured file-systems available in the kernel. In fact, you can have a system without ext2 support at all, provided you are using one of the other available file-systems, such as jfs, xfs, or reiserfs for all partitions. It is always a good idea to provide ext2 support if you are going to be using ext3, if only for recovery purposes.
All that being said, the help in the kernel's config/menuconfig/xconfig comes from the kernel developers upstream. The best place to have this changed it with them.
yeah, file a small bug upstream if you really want to see this resolved ...
the help doesnt *exactly* say you need to have it, but it is outdated with respect to talking about dosfs support vs ext2 support
