Description of problem:
Situation description: /usr mounted read-only, other mount points
mounted read/write, some package (e.g. mypkg.rpm) installed
(somewhere in /usr/...).
If I try to uninstall mypkg.rpm (rpm -e mypkg.rpm), it finishes
"successfully" (the package appears to be erased, rpm -q mypkg.rpm
reports "not installed"), but package's files of course persist on
the disk (mounted read-only).
I think this behavior is a bug. If the files cannot be removed, the
uninstallation process should fail.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Have /usr on a separate filesystem mounted read/write.
2. Install a RPM package which installs its files under /usr.
3. Mount /usr as read-only (e.g. mount -o remount,ro /usr).
4. Try to uninstall this package.
Actual Results: 1. The "uninstalled" package appears to be erased.
2. Package's files are at their places under /usr.
Expected Results: Uninstall will fail, reporting something like
"Uninstall failed - cannot remove files placed on read-only
rpm does "best effort" erasure, attempts, prints erro
in debugging spew, then continues.
"best effort" is the better approach because install/upgrade
are what people mostly use rpm for, not pure erasures.
