Changing ownership of the LFS partition

Now we're in chroot, it is a good time to change the ownership of all files and directories that were installed in chapter 5 back to root. Run the following commands to do so:

cd / &&
chown 0.0 . proc &&
chown -R 0.0 bin boot dev etc home lib mnt opt root sbin tmp usr var

Depending on the filesystem you created on the LFS partition, you may have a /lost+found directory. If so, run:

chown 0.0 lost+found

These commands will change the ownership of the root partition and the /proc directory to root, plus everything under the directories mentioned in the second line. In these commands, 0.0 is used instead of the usual root.root, because the username root can't be resolved because glibc is not yet installed.
