xCAT does that for you, the problem was with how xCAT builds the
osimage it will push out onto the Phi cards. For some reason when it
initially generated the passwd file for the Phi cards that users was
Xiao Peng Wang, the xCAT dev who is looking after this code, said:
# Thanks for your finding. I'll change the code to make the
# /etc/passwd file keep the micuser userid.
So hopefully it'll be OK in future releases of xCAT.
Now I just need them to implement a way to automatically roll out NFS
mounts into the Phi images. :-)
