The mainline CVS trunk is the "top-of-tree" and on any given day may not be stable on any given combination of OS and hardware but is generally quite stable. It's expected, of course, that anyone disrupting stability will help address the problem for other developers.
In addition to the trunk, branches may be freely created by those with write access to the CVS tree for potentially destabilizing development or when "quiet time" is needed for an implementation. We do ask that branches be listed here. Current list of branches:
stable_1_for_udi101
is maintained by Caldera and
focuses on the OpenUNIX 8 and UnixWare 7 OSes. At various times, this
thread has served as the basis of the SCO UDI Feature Supplement for
UnixWare 7.1.1 and the UDI implementation that appears in OpenUNIX 8.
Development on this branch is actively merged into the trunk. It's
maintained here in the open as a service to those working with UDI on
those platforms.
