Questions about the kernel version given to GLibc when configuring it.

Hi there forum. I'm curious about the configure options of GLibc in LFS. Specifically the --enable-kernel= option. In the current version of the book (8.2) it's passing it 3.2. Why is this? The kernel being installed in the book is 4.15. Why 3.2 and not 4.15, or 4.0, or any other? What is the rationale for selecting this version?

Thanx :-)

That would be the minimum kernel version to use.

Well, yeah. But my question was (and I thought I was clear in my question): why? That option cuts off workarounds for kernels older than the given number. So why 3.2, an ancient kernel at this point, and not 4.15.3, which is the one being installed?

It,s just a minimum version, Incase the HOST is using an older version, Also if you make it the latest kernel and you have to revert back to an earlier kernel you cant, You can make the "--enable-kernel=3.2 " 4.15.3 if you want it will still work,
It' called flexability.

You can't chroot from a distro with an older kernel than that one.
