SUMMARY: can we upgrade just one host to 4.1.2?

In <janet.701580034@dunnart> (yours truly) asked about this.
If you need to refresh your memory, my original post is quoted at the end.

The concensus on this is, YES! The only caveats people have given are:

The 4.1.2 system will be mounting the 4.1.1 man pages. Man will work,
of course, but your man pages will be a little out of date.

The only little problems you may see might revolve around programs that
have an intimate knowledge of the kernel, like top, etc. which may need
to be recompiled for 4.1.2.

If you have people who compile stuff that must run on all machines, make
sure they don't do the compiles on the 4.1.2 machine. Otherwise users of
4.1.1 will get the dreaded warning about library versions.

Thanks to all the people who responded - so many positive responses, it
must be OK!
