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} case $(uname -m) in x86_64) chown -R root:root $LFS/lib64 ;; esac
