[dougsland]

The setup set this dir and it's kept in the OS after package removed.

[root@localhost ~]# rpm -qa | grep -i qm

file /usr/lib/qm/rootfs is not owned by any package

also noticed this selinux complain after the package was removed looking the logs:

Apr 27 10:55:45 donald.medogz.local setroubleshoot[3346]: SELinux is preventing /usr/lib/systemd/systemd from search access >

                                                          If you want to fix the label.
                                                          /usr/lib/qm/rootfs default label should be lib_t.
                                                          Then you can run restorecon. The access attempt may have been stop>

                                                          If you think this is caused by a badly mislabeled machine.
                                                          Then you need to fully relabel.
                                                          Do
                                                          touch /.autorelabel; reboot

should we remove during dnf remove qm -y like rm -rf /usr/lib/qm?

Why not add qm and rootfs directories spec file?

[dougsland]

Why not add qm and rootfs directories spec file?

Agreed. I did. I just added a patch to setup to remove it as it was setup which added it in first place. Also, users in the future might want to decide to use a different path so the rpm needs to be adaptable. I will send the PR in few minutes.
