The commands in the remainder of this book must be performed while
logged in as user root and no
longer as user lfs. Also, double
check that $LFS is set in root's environment.
Currently, the whole directory hierarchy in $LFS is owned by the user lfs, a user that exists only on the host system.
If the directories under $LFS are kept
as they are, the files are owned by a user ID without a corresponding
account. This is dangerous because a user account created later could
get this same user ID and would own all the files under $LFS, thus exposing these files to possible
malicious manipulation.
To address this issue, change the ownership of the $LFS/* directories to user root by running the following command:
chown -R root:root $LFS/{usr,lib,var,etc,bin,sbin,lib64,tools}
