SUMMARY: Serial console vs. RSC console

Many thanks to those that responded and suffered thru my replies. 8-)

First of all, I received many answers that there is NO difference 
between the RSC console and the serial console.  The console is the 
console. Nuff said...

I finally figured this one out.There were two different issues on two 
servers.

Server #1
=========
Originally, I went into the OBP, ran nvedit and looked at the lines and 
did not see any problems. What I failed to do was look at ALL of the 
lines. I merely stopped at the first blank line thinking it was the 
last. In nvedit, I found that Ctrl-L will list all of the lines. I found 
this:

{0} ok nvedit
    0: devalias test2 test2
    1: devalias vx-rootdisk1 /pci@1f,4000/scsi@3/disk@0,0:a
    2: probe-all install-console banner
    3: cd /pci@1f,4000/scsi@5
    4: 6 " scsi-initiator-id" integer-property
    5: device-end
    6:
    5: device-end
    6:
    7:
    8:
    9:
   10:
   11:
   12:
   13:
   14:
   15: devalias vx-rootdisk2 /pci@1f,4000/scsi@3/disk@1,0:a
   16: setenv boot-device vx-rootdisk2

Apparently, some lines were erased but not deleted and I completely 
missed them.

Server #2
=========
This one was a bit easier to find since use-nvramrc? was set to false. 
I found a /etc/rcS.d script that had this line in it:
eeprom boot-device rootdisk-p rootmirror-d
The reason why it was intermittent was because I didn't boot all of the 
time. I had set auto-boot? to false to troubleshoot.  So, this would not 
hit until I actually did a boot.

This is what you get when you inherit systems.
Cheers, Rick

Original question
=================
We're running across some strange behavior.  We are setting aliases and
noticed something strange.  If we set the aliases from a serial console
they stick across reboots.  If we set them from the RSC console then
they revert.  Is there a difference between the serial console and the
RSC console (other than how you get in obviously)?  This makes no sense
to me because it's the same OBP.
