Re: Still haven't separated OS and Data

You must have been using a numpty distro. IME it is normal in linux distros, but it is a distro rather than kernel option.
It's been a few years since I've tried, but windows used to make a hash of it, since drive space was calculated at the "drive letter" level - directory mounted volumes appeared to be a kludge.
Also, separation is not as useful under windows, since the UIDs are unique to the installation and you'll end up with "unknown user" which isn't easy to fix (unless you've got central authentication running from somewhere else) since user data appears to be scattered all over the system - file and registry.
For example, I keep a spare partition so I can do a clean install to a different partition for a major upgrade and just remount the user directories. I made the mistake of trying to do the same thing for a windows install. I suspect there is a migration agent somewhere which will do it cleanly, but linux... well it's just less hassle. I also tried changing the "special folder" location - that didn't go well.
I'm sure all this stuff can be done under windows, it just seems like more trouble than its worth.
