If you are using a "modern" distro (with devtmpfs and a modern udev
implementation), a bind mounting is actually not needed because you can
mount devtmpfs anyway. The only reason for bind mounting is to be
compatible with old host distros where /dev is a directory containing
many static device nodes, or is a tmpfs (not same as devtmpfs) popluated
by bootscript or an old udev (modern udev implementations, including
eudev and systemd-udev used by LFS, strictly requires a devtmpfs on
/dev).
So update the explanation to match the status quo.
Update to meson-0.58.0
Update to systemd-248
Update to gcc-11.1.0
Update to linux-5.12.1
Update to iproute2-5.12.0
Update to Python-3.9.5
Make /bin, /sbin, and /lib symlinks to their counterparts in /usr.
Thanks again for a significant portion of this work goes to Xi, I only
really merged it and made a couple of modifications for my updates. To
LFS 11.x we go!
