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 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), 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!)
