Well, it's pretty similar.  I'm not sure if I messed up the installation
or not, but I had to later download reops--it has yum, chkconfig,
service and so on. 

I didn't find a samba package, but as this was for one oracle developer
to transfer files, we just used winscp.  (I also didn't look hard for a
samba package, at present, this is just a test.)

Disk naming seems slightly different--we went with more standard
partitions rather than LVM, and rather than /dev/sda and so on, it was
/dev---arrgh, I'm not at work, and my mind just went blank--errm, xda
and xdb?  At any rate, it will be fairly obvious. 

As mentioned, this is a test, and while I don't know all the
circumstances, we're not entitled to support--if you do it officially,
as opposed to what is probably a trial version, there is support, and I
assume (but note, that's an assumption, not knowledge), one could call
and ask things like, Where can I find samba? 

(Samba client and samba common was available, but no smbd.  Again, I did
NO googling on this, just did yum provides */smbd, got no results, and
then used WinSCP.)

There won't be any major shocks.  On the other hand, in our case,
there's nothing at all tricky for my part of it--I just had to get a
basic server running for the oracle developers to use.
