RPM succeeds when trying to uninstall from a readonly filesystem

From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; es-ES; rv:1.7) Gecko/20040803 Firefox/0.9.3 Description of problem: I have /usr mounted as read-only, and I only mount it read-write when I make changes to it. However, I once forgot to mount it as R/W before trying to uninstall a package. RPM just told me that it succeeded uninstalling the package when, in fact, it didn't succeed. I realized the package wasn't uninstalled days later. I don't know whether this is the intended behavior or not, but RPM should at least report something like: - "Just for you to know, I couldn't uninstall [this_package] because the filesystem (is readonly / didn't allow me to)", so one can either ignore the warning or make further necessary steps. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Mount /usr r/o 2. Uninstall any package installed 3. Check for uninstalled package. It will still be there. Actual Results: RPM reported "Uninstall succeeded". Expected Results: RPM should have reported "Couldn't uninstall the package". Additional info:
Yep. rpm does not check for RO mounts, and rpm --erase is "best effort" i.e. rpm will attempt to erase, but will not terminate if a unlink(2) or rmdir(2) system call fails. This behavior is as intended.
