F41 systemd tmpfs mounts

I have upgraded my triple boot laptop (standard ext4 filesystem)
from F40 to F41 without any problems.

However now a simple ‘df -h’ command produces a whole swag of
tmpfs 1.0M 0 1.0M 0% /run/credentials/systemd-*******
in addition to my normal /etc/fstab entries ??

These annoying tmpfs entries by can be easily hidden
(e.g. df -h | grep -v service) but this is a cosmetic kludge.

I was hoping to find the real reason why would systemd mount
these in the first place.

Any advice appreciated.

You could have read the man page for df to see if there are any options you can use.

The --exclude-type (-x) seems to do the trick.

$ df -x tmpfs -h

There’s some general documentation here - Credentials
And a better list of what some of the individual credentials are used by/for: systemd.system-credentials
