I’d still use LUKS. Even on USB keys.

I still wouldn’t use Veracrypt on a Linux disk. What about LUKS instead?

If you’re only using the external disk for days you could use ntfs with bitlocker and mount that in Linux. When your rest to fully migrate you could then do something Linux only if you wanted.

I’ve always said this to people. I use Windows, Linux, and MacOS. I use whatever best suits what I’m doing and I like that idea. It may end up being 20/70/10, but so what. Why battle a shitty Linux app If you have a good MacOS app. Or maybe your liking that windows app for a certain task.

In reality this is really only something a dev or power user would really do though.

I had an issue where my docker networks started overlapping my network addresses and I had some issues to connect to the machine etc. so perhaps check to make sure your docker addresses don’t overlap your home network range somehow. Also keep the subnet mask in mind as the range might be bigger than what the first few numbers indicate.

I have no idea what types of files these are but it could turn out that you should rather use Git and push/pull from both sides which could works better.

Just a suggestion :)
