Message:

kernfs: Use a separate devpts filesystem for chroot environment

IIRC we switched from separate devpts to bind mount, and matched the UID
of tester with the host UID owning the TTY, to satisify the Bash test
suite. But now we are always using UID 101 for tester and expect to
spawn a PTY for Bash test suite (so when building LFS in a TTY owned by
the root user of the host tester won't be UID 0). Thus we can switch
back to a separate devpts mount which is cleaner and safer.

And we are already using a separate devpts mount in Chapter 11.
