Hi, hope someone can explain why this could have happened before I spend any more time...
I've built SLES11SP2 xen hosts from autoyast (autoyast is just from the "clone" at the end of the install)
the entry:
hosts: files dns
appears to have gone missing from /etc/nsswitch.conf on the machines built from the autoyast.
The line is there on the machine the autoyast was taken.

Could a patch have removed the line?
I guess it "should" be there?
