Yep. I've experienced on several computers that the systemd-approved "predictable" network device name changes when adding or removing a SSD. The solution is to turn off the network device renaming and allow the single ethernet interface in the machine to always be known as eth0.

systemd developers like to come up with clever solutions to the problems they care about, and ignore the side effects for any use cases they don't care about. And quite often those afflicted use cases are the ones most people would consider to be the more typical use cases.
