[Beowulf] Diskless Phi node installs?

Hi folks,

Our new diskless Intel cluster has 10 nodes with Xeon Phi's in them,
and I'm wondering if anyone has had any luck with getting the extra
bloat out of the RAM disk?   We're using xCAT to manage the cluster.

Basic problem is none of them support relocation:

[root at old-barcoo-m knc]# rpm -qip *.rpm | grep -i relocat
Name        : intel-mic                    Relocations: (not relocatable)
Name        : intel-mic-cdt                Relocations: (not relocatable)
Name        : intel-mic-flash              Relocations: (not relocatable)
Name        : intel-mic-gdb                Relocations: (not relocatable)
Name        : intel-mic-gpl                Relocations: (not relocatable)
Name        : intel-mic-kmod               Relocations: (not relocatable)
Name        : intel-mic-kmod               Relocations: (not relocatable)
Name        : intel-mic-micmgmt            Relocations: (not relocatable)
Name        : intel-mic-mpm                Relocations: (not relocatable)
Name        : intel-mic-sysmgmt            Relocations: (not relocatable)

They chuck all their stuff onto the local filesystem so you get about
1GB of extra stuff on an image compared to a non-phi node (which only
lacks the Phi related RPMs).

The only one you need to deal with is the intel-mic-gpl RPM as that has
the Linux distro for the Phi in it and so has the largest footprint (way
over 700MB) and includes compilers, etc.

All the best,
