Hi there,

I used a little bazaar plugin [1] to do this.

Then ran:
  $ bzr append-only lp:compiz

So compiz trunk is in append only mode now, so rewriting history is not
allowed.

You need to have write access to the branch to use this command.

Cheers,
Tim


[1] -- put the following in ~/.bazaar/plugins/append_only.py

from bzrlib.branch import Branch
from bzrlib.commands import Command, register_command


class cmd_append_only(Command):
    takes_args = ['branch']
    def run(self, branch):
        """See `Command`."""
        b = Branch.open(branch)
        b.lock_write()
        b.set_append_revisions_only(True)
        b.unlock()


register_command(cmd_append_only)
