Issue with "temporary" option of nmcli mod

[Abbott Clark <abbottclark2020 gmail com>]

Hello,

    I am trying to set the below temporarily:
      nmcli con mod --temporary  ep65s0f1 connection.autoconnect yes

    The connection.autoconnect is correctly set to "yes" in memory and
the ONBOOT option in the ifcfg-ep65s0f1 file is still "no" as
expected.

    However after the above command, if I modify any other parameters, for e.g.
      nmcli con mod ep65s0f1 ipv4.never-default yes

    the ONBOOT option in the ifcfg-ep65s0f1 file is set to "yes".

    Can I please know what is the correct way to set
"connection.autoconnect" in memory only and not have NetworkManager
write the temporary configuration to the ifcfg file on subsequent
configuration changes.

Thanks
Abbott
