Notes of the LFS making(Fin)

I focused on the LFS about a week, I have finished installed the LFS, It can boot and work very well.
In fact I can finish it in 2 days, but I made some mistakes that shouldn't happen to me.

I didn't read the Notice on the LFS handbook. so I paid!
Most important: check the $LFS, and chroot (Esp when u reboot the PC).

When U install the Perl, U may face this problem:
Updating man page uname.1

Check the $LFS and chroot. :-)

Most of the check is no need, except the ones needed. :-)
Also, I cp the cmd to the shell. Wish U good Luck on the LFS!
