Comment:
I worked with upstream on this (see https://github.com/netblue30/firejail/issues/4387; the problem was that the `MS_REMOUNT` flag was not being cleared before some calls to `mount`).
The upstream commit `ba5f5c8` should fix this bug, as I verified by manually patching /usr/bin/firejail to match that commit (clearing the `MS_REMOUNT` flag before the call to `mount`).

I expect this will be fixed in the next firejail release.
