Not wholly - in BLFS we started (a few years ago) by installing the
binary, then rebuilding from source : at that time the people doing
it did not know we could install texmf and then (most of) source.
So, our installs went into 20xx/bin/i386-linux or
20xx/bin/x86_64-linux.

Thanks, but for BLFS users who build from source the next update
will normally be a fresh install of 2016.  If our users want to keep
up to date with the latest and greatest, they can use the binary
installer.  Please note that we are somewhat different from many
distros: we like stable releases of packages, unless there are
compelling reasons.
