[comp.sys.mac] A/UX Eschatology Question

buzz@phoenix.Princeton.EDU (Mahboud Zabetian) (03/05/88)

What is the difference between escher and eu?  I know that eupdate just updates
certain files.

What is the difference between Eschatology 1 partition and Eschatology 2
partition?

Is there anyway to read from those partition while running A/UX(not sash,
A/UX)?  ( I think I can mount them.  Am I right?)

Thanks.

Yep, escher goes through and updates certain files (it uses the cml file
to figure out what to update, but I can't remember where it is in the 
filesystem right now...), and eu will update a single file and/or add
a new file to the Eschatology partitions, as well as the cml file for escher.

I'm not sure what the exact difference is between the two partitions, but
the idea is to have two copies of the critical files at different parts of the
disk (Eschatology 1 at the front and Eschatology 2 at the back of the disk)

Yes, you can use pname to associate the partitions to a slice, then mount
them, BUT, as I understand it, you do not want to do this.  If the partitions
get modified "behind their backs", Eschatology is not too happy about it.  You
should let the autorecovery utilities mess with these paritions.

Of course, I'm not in the A/UX development team, I just have 2 A/UX boxes
in my office and I'm supposed to know how they work... :-), at least enough
to have them boot whenever....
