Re: Having ten thousands of mount bind causes various processes to go into loops
> Does it have some logic to avoid descending into bind mounts? Maybe I am wrong with my expectation that it does not use anything besides st_dev from stat result. It may be promising case to demonstrate the issue in a way independent of systemd and sandboxing. You can obtain command line arguments. Attach to its mount namespace and inspect content of its /proc/<PID>/mounts or mountinfo. The next step would be to profile or at least to trace a process.
I'm not sure i understand you there.
> I have not figured out from your description what problem you solved by using bind mounts, but bublewrap (so flatpak and snap) and firejail relies on bind mounts as well. Perhaps you have some unique factors.
Mounts are used as a way of sharing folders in different users' home
directories.
For instance you would have : /users/bob/accounting shared with Alice
and accessible in her home directory /users/alice/accounting
Thanks for your help :)
