[Bug 32428] New: Support loading/appending optional registry files

http://bugs.winehq.org/show_bug.cgi?id=32428

             Bug #: 32428
           Summary: Support loading/appending optional registry files
           Product: Wine
           Version: 1.5.19
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: scott(a)open-vote.org
    Classification: Unclassified


It would be useful for me to have a wineprefix be a system-level read only
folder and be updated by system package installation.

In order for this to work with user data, however, a copy-on-write filesystem
needs to be introduced (eg unionfs-fuse) that creates a union between the
read-only packaged prefix and a user-level folder; newer versions of files will
end up in ~/.appname or similar.


This breaks down, however, with Wine's implementation of the registry as a few
flat files.  Consider:

Version 1.0 of package has x in user.reg
User runs the app and appends "foo" to registry.
Package is updated to version 2.0 which has "bar" added to user.reg.
Because user.reg already exists in ~/.appname, this user will forever have
"foo" but not "bar" unless he deletes ~/.appname (or at least user.reg
therein).


One solution would be an environment variable to have Wine write/load new
registry entries to a different filename, eg ADDITIONAL_WINE_REGISTRY=local.reg
 -- then Wine would load its registry files as normal, but supercede them with
any newer entries found in local.reg.  This way local.reg could be in
~/.appname but not the packaged read-only prefix, and "the right thing" would
happen with any application updates.
