Copy lmod from compute node to master node

# cp -r /opt/ohpc/admin/images/centos7.5/opt/ohpc/admin/lmod/ /opt/ohpc/admin/

Copy lmod.sh from $CHROOT/etc/profile.d to /etc/profile.d

# cp -r $CHROOT/etc/profile.d/lmod* /etc/profile.d

Change vnfs.conf for copy locale folder to compute node by add "#"

# vi /etc/warewulf/vnfs.conf

#hybridize += /usr/share/locale
#hybridize += /usr/lib/locale
#hybridize += /usr/lib64/locale
