All of us here have run into the same problem.  There are probably only two
ways around it.
- Do any editing of files (read "copies of files") before taking the system
down to runlevel 1, and move them into place.
- Use 3270 console mode and buy the NED full screen editor from UTS Global.

With Linux/390, the basic requirement is that if you're not willing to do
#2, then you need a working network connection to be able to do useful work.

Subject: Questions regarding single user mode and z/VM


I am new to this group as well as (what we have come to call) zLinux
running on z/VM.  However, I was tasked with the POC (Proof of Concept)
project given my strong Linux and Unix background.  Our POC involves an
installation of z/VM 4.3 and Suse Linux SLES - Timer 7.2.  In working in
this environment the first thing I notice are issues around z/VM and Linux
in single user mode.  These issues include the following:

-> vi is out
-> paging (less / more) is out
-> "  == Escape character in regex statements v. \
-> # == NL in regex

It seems all of these issues are tied to the simple issue of terminal
emulation.  Given my background with Unix I certainly understand that
single user mode is a must for any Linux (Unix) installation.  The reasons
to be able to support your VM (guest install) from single user mode is too
numerous to list as is the case with Unix installed anywhere.

Has anyone else seen these problems and are their ways to fix them (the
issues)?  I have figured out how to get around them with some interesting
perl commands, vi <file> << EOF statements, and sed commands.  Now rather
than be crafty I would like to actually be able to do my job the way I can
on any other platform.

Thanks!
