Hi, I'm sorry for the trouble that running mmdebstrap as superuser caused. I'm glad that no data got lost!

I now added a commit that mounts a completely new sysfs when not running in unshare mode and doesn't use the --recursive when unmounting: https://gitlab.mister-muffin.de/josch/mmdebstrap/commit/640d854c2e0f139fdfbd60ddaffc5dfe72063fc0 If you are okay with that, I'd be happy if you could verify that after adding this patch, the problem indeed disappears.
