It is currently difficult to maintain (update) a trunk checkout with some
modules switched to a branch. With the "Use update" checkbox selected:

1. if Hudson is configured to check out the trunk (and a build script is used to
the switch some modules to a branch ), when it does an update it will use a -D
CVS option, which will switch the branched modules back to the trunk.

2. if Hudson is configured to check out the the branched modules (and the rest
of the modules is checked out by the build script), when it does an update it
will switch everything to the branch because it will use a -r option for all
modules.

The option to turn off -D described in issue 229 would help if Hudson was
configured as in #1, but generate no changelogs for the branched modules.

I suggest the introduction of an option to allow Hudson to update just the
modules specified in the "Module(s)" list. The UI could change from

[x] Use update

to

[x] Use update [x] only for the above modules

Of course, when the "only above modules" check box is selected, updating any
other modules in the workspace should be done by the user e.g. in the build script.
