        !             7: * [tuning for git on low memory](http://mail-index.netbsd.org/tech-repository/2015/01/08/msg000520.html)
1.1       mspo        8: 
                      9: git appears to have slightly different memory characteristics depending on the
                     10: protocol used.  Over http I am able to get a full clone with all history on a
                     11: 256 + 256 raspberri pi.  If you bump up the memory to 512 + 256 it makes ssh
                     12: possible, which means writes are possible.
                     13: 
                     14: The link above has some tuning I used to get memory requirements way down.
                     15: 
                     16: It should be noted that git support a "shallow" clone (--depth 1) which ignores
                     17: most history but allows commits and full development.
                     18: A shallow clone works on very small systems; I would guess 128MB + a little swap
                     19: is enough.
                     20: 
                     21: git is slow during 'status' by default since it searches the entire tree for a
                     22: change.  It will produce a warning with tunable options if the command runs
                     23: slowly.
                     24: 
1.2     ! mspo       25: ### CVS in parallel
        !            26: 
1.1       mspo       27: I do not think this is a good idea and do not plan to advocate for it.
                     28: Git does have a cvs server built-in but I have not taken the time to set it up
                     29: for testing because it is slightly involved and I don't see the purpose.
                     30: 
1.2     ! mspo       31: ### Conversion
        !            32: 
1.1       mspo       33: One-shot to create the new True Source.  I don't think there will be many cvs
                     34: hold-outs.
                     35: 
                     36: See above for CVS server provided if ongoing conversion is really desired.
                     37:

        !            43: 
1.1       mspo       44: High level- private box for write master using ssh, any number of additional
                     45: systems with read-only mirrors over http:// and git://
                     46: 
                     47: Also see a great description of how DragonflyBSD is setup:

        !            52: ### how to install
1.1       mspo       53: 
                     54: git should fit into NetBSD src/tools easily.  I have not personally tested
                     55: cross compilation.
                     56:

        !            58: 
1.1       mspo       59: See DragonflyBSD examples given above
                     60: 
                     61: There are many many workflows supported in git.  For the most part I think
                     62: NetBSD developers would follow the "feature branch" workflow from the main repo
                     63: (or private/semi-private clones before merge).
                     64: 
                     65: Public collaboration is a big feature of git since it can format patches into
                     66: at least two different email formats and they can be submitted to a bug report
                     67: or to a mailing list, which should allow clean apply.
                     68: 
                     69: A non-developer could also post a pull request to github or host his git repo
                     70: for a friendly developer to add as an origin and pull his branch.
                     71: 
                     72: (git origin add future-developer http://example.com/~greatguy/src.git)

        !            76: 
1.1       mspo       77: Try to references named branches instead of sha-1's
                     78: Also using the dates for commits instead of commit id's
                     79:

                     83:

        !            85: 
1.1       mspo       86: I am unable to anticipate the next generation of SCM.
                     87: Don't do anything weird like change history and we should be fine.
                     88: 
                     89: Maybe when we have 30 years of project history it will be time to consider
                     90: restructuring the project.  :)

                     95: * sometime, eventually, maybe
                     96: * unknown
