Yeah that sounds like a good solution. I think arch based pikvm does something similar. (no reboot necessary to enable rw)
For those pis that need to write stuff, I usually mount a network drive and use that while having the overlayfs enabled. So far haven’t had any issues, only one pi died after 3 years due to faulty power supply.
Try to use overlayfs under raspi-config, I’ve been running some raspberry pis for years with that (mostly on offsite locations where fixing dead sd cards is not possible)
Updating the pis is a little more work but in some use cases it’s worth it
Don’t know why but for some reasons I cannot take people seriously that write articles about the importance of their role.
In the media, CTOs are often portrayed as tech geniuses or wizards, single-handedly coding complex algorithms or inventing groundbreaking technologies. Not sure what kind of media the author of this articles (op?) consumes, but I don’t know anybody who thinks something like that.
