7.2. Changing Ownership
![[Note]](../images/note.png)
Note
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 and files under $LFS
are kept as they are, they will be 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,tools}
