xCAT 2.8.5 stateless bug

When trying to create a stateless xCAT image using the following commands:

1. genimage centos6.5-x86_64-netboot-compute
2. packimage centos6.5-x86_64-netboot-compute
3. nodeset n1 osimage=centos6.5-x86_64-netboot-compute

The following error appears when trying to boot the node:

dracut: FATAL: No or empty root= argument
dracut: Refusing to continue
/lib/dracut-lib.sh: line 101: /emergency/01-die.sh: No such file or directory
dracut Warning: Signal caught! (when trying to boot the machine).

The problem is that there is a directory missing, it was skipped by xCAT installation for some reason, therefore, we need to create it manually:

1. cd /opt/xcat/share/xcat/netboot
2. ln -s ../rh/dracut dracut

Repeat the three commands above and you all set to go !
