  4. It's time to enter our chroot'ed environment in order to install the
  5. rest of the software we need.

  8. Enter the following commands to enter the chroot'ed environment. From
  9. this point on there's no need to use the $LFS variable anymore, because
  10. everything a user does will be restricted to the LFS partition (since / is
  11. actually /mnt/lfs but the shell doesn't know that).

  19. The -i option will clear all environment variables for as long as you
  20. are in the chroot'ed environment and only the ROOT and TERM variables
  21. are rest. The TERM=$TERM construction will set the $TERM value inside
  22. chroot to the same value as outside chroot which is needed for programs
  23. like vim and less to operate properly. If you need other variables
  24. present, such as CFLAGS or CXXFLAGS, you need to set them again.

  27. Now that we are inside a chroot'ed environment, we can continue to
  28. install all the basic system software. You have to make sure all the
  29. following commands in this and following chapters are run from within the
  30. chroot'ed environment. If you ever leave this environment for any reason
  31. (when rebooting for example) please remember to mount $LFS/proc
  32. again and re-enter chroot before continuing with the
  33. book.

  36. Note that the bash prompt will contain "I have no name!" This is
  37. normal because Glibc hasn't been installed yet.
