I already think the answer is no, but asking the big brothers here.

I was intending to use an nvme SSD with enclosure I have, as an external portable OS so that I plug it in any machine I find, ask for boot menu and run my own “computer” that I can simply transport. I was planning to use fedora as I heard it’s driver support is quite wide.

Now, as some of my family members use macbooks, I thought it would be awesome to have two of the same OS but arm and x86 variants that might share a user folder for config and then have an exfat partition for data so both can use it and also the drive would work as an external drive (backup option in case I need to use the native OS of the machine for some reason).

I’m seeing that this is really not as simple and a search for similar settings didn’t through any result. So:

Is this at all possible? Is it practical? Any ideas of solutions? I thought about syncing scripts that automatically update and log changes from one os to the other, but seems very limited due to architectural differences in paths and libs.

Thanks a lot!
