password-store /dev/shm mfs

Hello,
I'm a happy new user of OpenBSD since 7.7 on my lenovo t470 laptop.
This is my first message to the list, hope it is appropriate.

When I try to edit a password with pass, I receive this warning:

"Your system does not have /dev/shm, which means that it may
be difficult to entirely erase the temporary non-encrypted
password file after editing."

However, I put my tmp on mfs, does this solve the problem?

Thank you,
Regards
David
