OK, a bit of context. I'm starting the UML inside a small LFS system
running in text mode under VmWare. I just tried

Hello,
Thanks for your advice!!!
I installed KDE but then used VNC-Server because it seemed easier than
X Windows/Servers.
Thanks again!

Hello,
Apologies if my question is too simple for you :-)
I have a server (accessible only via SSH really) and I want to run a
UML instance so I can use some kind of VNC to connect to it. Is this
possible? I have experimented with X11 forwarding, but without luck.
Is this the way forward?
Thanks

after reading the (old) chapter on shared filesystems, some
admittedly basic questions on COW files. (i'm fairly sure i know the
answers here but i just want to play it safe.)
1) each filesystem i use as part of my UML session can have its own
COW file, right? as in:

Yes, that would also work.
I couldn't help thinking about larger strategies the followed from your
particular problem, I guess.

why would i need to do that as opposed to just removing *my own* write
(if there's a web page that covers this, a simple pointer to it will
do just fine.)
as a followup to thinking about UML and COW, how would i configure
and run a UML session using multiple filesystems? say i took the time
to create multiple filesystem images corresponding to the following
fil
Remove non-user write permissions from the root_fs file:
chmod og-w root_fs
And run the uml instance from a different user account than the owner of the
root_fs file.
In fact, if you are always using the same root filesystem, I would be tempted
to place it here:
/usr/share/uml/root_fs
and ma
currently, i'm reading the chapter on sharing filesystems here:
http://user-mode-linux.sourceforge.net/old/UserModeLinux-HOWTO-7.html
and i have a few (again, fairly basic) questions about running UML
using COW to protect the root filesystem from modification.
first, is there any way to tru
