Installing with read-only /usr
Since /usr is supposed to be able to be mounted read-only, how does dpkg
handle installing new packages?
Here is a possible problem, I think:
- I export my /usr filesystem read-only to my network.
- Others mount this as their /usr since they have tiny disks
- I install a new package on my system that also installes files in /etc
- Others can't install because they can't write to their /usr directories
- Others don't have a complete set-up because of missing files in /etc
Can dpkg be set up so if it detects a read-only /usr partition then, instead
of trying to put files in there, just verifies that those files aleady
exist before continuing with the rest of the installation?
