[gentoo-user] Questions on attempt at first install.

[Diagon]

Could someone clarify for me what `genkernel --menuconfig` is doing?  

Is it equivalent to a manual kernel config, only saving me the `make` && `make install`?

Or is it setting what `genkernel all` would set, and letting you modify that?

Do I run it as `genkernel --menuconfig all` ?  As `genkernel --btrfs --menuconfig all` ?

If I run `lsmod`, I see btrfs, but I also see that btrfs depends on: xor, zstd_{de,}compress, xxhash, lzo_compress, zlib_defalte, raid6_pq, and each of those may have their own dependencies.  

Do I need that whole chain for the kernel?

Thanks in advance!
