changing permissions of /usr running liveCD

[bernstine]

Hi!

I am running knoppix3.7 off the liveCD. I have downloaded the nzb news client. I've gotten the point where I enter "make install", but then I find that /usr/bin/knzb is read-only.

How do I change the permissions? And am I installing to the correct folder for my situation?

Any help is much appreciated! thanks

While running from the live CD, you can't make /usr read-write. It's not a matter of permissions, it's a matter of the CD itself being read-only. Except for a few directories that are created in memory, or loaded from a loopback file, if you're using a persistent home, most of the Knoppix file structure is read-only.

(AFAICT, different live CDs have different writeable directories. For example, in the Basilisk/Linux4all (http://www.linux4all.de/livecd/basilisk/1.40/) live CD, /mnt is read-only, while on Knoppix, /mnt is read-write.)

You can, however, grab the Knoppix 3.8 CeBit Edition (torrent on this tracker (http://www.boegenielsen.dk:6969/)), which, for the first time, uses UnionFS to overlay filesystems on top of each other, essentially making the whole filesystem read-write. Then you can compile and install your software while running from the live CD.

(Or, install Knoppix on your hard drive!)
