You can prepare a kernel config before launching jhalfs, with the same kernel
version as the one in lfs. Then there are not so many problems. But there may be
some. Here is an example I ran into today:
My host is debian 12, which has gcc-12. This version of gcc does not support
creating debug sections compressed with zstd. So this choice is not proposed.
But lfs has gcc 13, which does support that. So make oldconfig proposes this
option as (NEW), then stops waiting for the user choice... Note that for some
reason my kernel configs for VM's enable debug symbols in the kernel (a remnant
of when I had to debug the kernel a few years ago). This problem does not exist
if debugging is turned of.
With the new behavior of timing out if the build system is stuck waiting for
input, you are given a chance to enter chroot, configure the kernel again, save
the .config to /sources/kernel-config, exit chroot, then restart make.
