Description of problem: On Fedora IoT (32) I am interested in creating a specific profile for my onboard ethernet adapter. It appears that each time the system boots NetworkManager will create a profile automagically for that interface, so no changes via `nmcli` will take effect between reboots. Version-Release number of selected component (if applicable): How reproducible: I've reproduced on two Fedora IoT fresh installs. Steps to Reproduce: ``` [root@arbiter ~]# nmcli eno1: connected to Wired Connection "Intel Ethernet" ethernet (e1000e), F4:4D:30:6D:86:55, hw, mtu 1500 ip4 default inet4 172.16.0.8/24 route4 0.0.0.0/0 route4 172.16.0.0/24 inet6 fe80::f64d:30ff:fe6d:8655/64 route6 fe80::/64 route6 ff00::/8 lo: unmanaged "lo" loopback (unknown), 00:00:00:00:00:00, sw, mtu 65536 DNS configuration: servers: 172.16.0.1 interface: eno1 Use "nmcli device show" to get complete information about known devices and "nmcli connection show" to get an overview on active connection profiles.

Consult nmcli(1) and nmcli-examples(7) manual pages for complete usage details. ``` Actual results: "Wired Connection", although deleted previously... is now newly created upon boot (checking the timestamp shows it was created during the boot process). Expected results: System would "respect" the deletion of the automatic profile and begin using the manually specified profile. Additional info:
It's possible this is related to an issue[1] I found on F32 Server after upgrading from F31. My guess is that this automatic profile is generated as a result of NM trying to replicate a previously existing connection during boot, although I don't know how the IoT boot process works. This generated profile then overrides the manually created profiles. [1] https://bugzilla.redhat.com/show_bug.cgi?id=1829461
This message is a reminder that Fedora 32 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 32 on 2021-05-25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '32'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 32 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 32 changed to end-of-life (EOL) status on 2021-05-25. Fedora 32 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
