Move HOME directory to ZFS?

[jonhermansen]

Just wondering if anyone has yet tried moving their HOME directory over to ZFS, or if there are any suggestions on how to do so.

I have tried and failed a few times so far. It seems that there are a few approaches:

• Update ProfileImagePath for the user under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
• Junction point
• Folder redirection / roaming profile

Basically I already have my home directory shared across Linux and FreeBSD. I'm trying to figure out how to create or migrate a Windows user into a new home folder, after which I can migrate my Linux data into the same folder. I'd like to share with macOS as well but I presume that it shouldn't be a problem. (I apologize because I am not very familiar with Windows ACLs or what is required by Windows for user metadata)

If I physically move the HOME directory from another admin user, update the ProfileImagePath, then log in as the migrated user, Windows says it can not find my home directory and shows my temporary HOME dir is C:\Users\TEMP. It let's me log in, but my user session doesn't seem to have loaded anything from the migrated home dir, nor does it seem to persist anything

I was able to use folder redirection, but I found that only some home dir data was being stored there. Ideally I can store everything on ZFS (though it seems NTUSER.DAT requires special perms)

Instead of faffing about, I figured I'd try asking for help here. Thanks in advance to lundman and all contributors to the project.

What a nice aim. My total support for you, @jonhermansen.

As the first step, I'd try migrating home dir to another NTFS volume. When this works for you, only then I'd try switching it to a ZFS dataset.

The first approach, or rather namely "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\ProfilesDirectory"="D:\..." best should be done before the (first) user signs in, according to this thread:

If you boot using live media (WinPE or so), you should be fine with copying the dir and inserting junctions, as shown in one answer above:

I'm going to be very keen on the follow-ups here. Very practical challenge. Cheers!
