This is an example of the directory layout for the chroot/etc directory of a SELinux UML instance.
ld.so.cache should be generated with ldconfig -r.
localtime is not required generally, but adding it makes chrooting into a shell more practical.
Generally, nsswitch.conf can be copied from the host as is.
The pam configuration files are only needed if there are binaries that use pam.
