The
tar
command used in the "ROOTFS method" heading loses important permissions data.For example,
unix_chkpwd
(a program that uses the setUID bit to allow some lockscreen programs to talk to PAM) may have missing setUID permissions, leading to user lockout.Using only tar xvf
# ls -l /mnt/usr/bin/unix_chkpwd -rwxr-xr-x 1 root root 38880 Dec 26 2023 /mnt/usr/bin/unix_chkpwd
Using Gentoo-style tar extraction
# ls -l /mnt/usr/bin/unix_chkpwd -rwsr-xr-x 1 root root 38880 Dec 26 2023 /mnt/usr/bin/unix_chkpwd
This commit updates the documentation's
tar
command to match how Gentoo unpacks their tarballs.
