That seems reasonable.

star-merge with no parameters? Yeah, could work.

No, I don't like this. Thats no longer the same line of development.

To me, this is a config management issue, and easily solved there:

have a branch- say address@hidden/rhythmbox--dists--1.0
which contains
configs/rhythmbox/mainline
configs/rhythmbox/mainline-0.5
configs/rhythmbox/mainline-0.6

where mainline is a symlink to -0.6.

and 0.6 contains:
./rhythmbox address@hidden/rhythmbox--mainline--0.6

so a config iteration will update against the correct named version
$ tla catcfg configs/rhythmbox/mainline | xargs -n2 | tla replay -d

Now sure, a little scripting to make this transparent to the user may be
in order. But it's definately not a core tla thing as far as I am
concerned.
