I have a problem...
For example when I try to modify /etc/motd my editor says, it's read-only.
Ok. I'll try to chmod. Nope. Does not work. Even if I'm root.
At some cases it says: read-only filesystem.
I guess I have to copy it to /ramdisk to make it writeable? But that's not enough I guess.

I saw a script somewhere named mkwriteable. Could this be a solution to my problem?

yep, that would copy more of the base system read-only image to ram.

another way would be to copy the file and delete the sym-link.

Hmm. That could also be the answer for my other problem with Firefox.
When adding new search engines to FireFox menubar nothing simply happens.

Anyway. Thanks for this info.

Actually, mkwritable does not make the /etc directory writable, it alread IS writable.

However, there are two limitations to the existing configuration:

1) Many of the files require Super User ("root") authority in order to edit or delete them.
2) Many of the files are actually symbolic links (kinda like MS Window's "shortcuts" but better) that point to the real files.  The real files are located on the CDROM disk so they are read-only.

However, you can still fix this problem manually:

Open "Emelfm as Super User"
Go to the /etc directory.
DELETE the /etc/motd file link.
In the other window pane, go to /KNOPPIX/etc and copy the motd file over to /etc

To edit it, Right-Click on the file and choose User Edit in Beaver and you are in business.

I did that and it worked.

Some of the files are links to files in RO area.
That's why I couldn't change it.
