https://unix.stackexchange.com/questions/554240/unshare-mount-inside-a-jenkins-chroot-environment seems to be right on the money... or at least relevant: / inside the chroot is not an actual mount-point.

Moving the / remount to the rpm parent process makes it work, but then that has other side-effects and causes one test to fail. That rabbit hole may be deep, and it's not something we can afford to dive into just before an rc.

Dropping 4.20 milestone, that ship sailed already. There's always the next update.

@pmatilai Hi, is there any workarounds without re compiling rpm?

pmatilai commented 3 weeks ago

Just uninstall the plugin? Or use --noplugins for chroot operations.
