  povray vs. DSL-N linux (Message 1 to 5 of 5)

I successfully installed DSL-N linux to a USB pen HDD drive.

I then booted up DSL-N and tried to install povray.

I get some error messages, not of which all I could read. One of them is

"mkdir: cannot create directory '/user/local/etc/povray': Read-only file
system "


It happens whether I'm in root user mode or regular user. So is this the
"fault" of povray's ./install,  DSL's design, or my failure to RFTM?

TIA for help.

A "feature" of DSL.

	Looks like the solution mentioned there means some extra parts of
the DSL filesystem are copied to RAM.  I conclude that installing POV-Ray
on this system is done in RAM as well, not on the usb pen.  Thus, you will
have to install it each time you boot your distro.  Is it correct?

I think you're right.
In fact it's a little bit like other live distros : you create a system 
image wich is loaded at startup.

Generaly, there is a part of the filesystem wich is mounted in RW mode 
to allow users to have theire own files, perhaps could you install 
povray on this filesystem (./configure --prefix=/path/to/my/home/direct
ory)

Another solution is to install your live distrib on a hard disc, to 
modify it's content (like installing povray) and then rebuild a live 
version of it for your usb pen.

I've been thinking of doing the same thing. Either with DSL or Puppy Linux.
I've got Puppy installed on my HD, but I don't really know that much about
it yet. Simply Mepis is my main Linux distro.

I hope you get this little problem worked out, Greg. Maybe Christoph H will
have some suggestions, too.

When running POV from the USB, I'd suggest using a temporary RAM file for
the scene file you're editing & the output image files. Flash drives are
great to read data from, but excessive writing will prematurely age them. I
believe DSL has features to help with this issue, IIRC.
