[Xorp-users] Will Quagga/Bird conflict with XORP when both are installed?

As long as you run your routing protocols on separate ports/interfaces 
(and configure
everything explicitly to do so), all should be fine.

This entirely depends on the distribution / OS you are using. FreeBSD 
ports for example set CONFLICTS
for Quagga and XORP, which is not a XORP issue.

XORP's Router Manager process, xorp_rtrmgr, has a daemon mode. We don't 
currently use this
in the LiveCD or LiveUSB production builds, however, you can certainly 
daemonize xorp_rtrmgr
by passing the appropriate command line parameter (off the top of my 
head, I think this is -D,
however running xorp_rtrmgr -h should tell you the command line parameters).

Note that the protocol processes invoked by xorp_rtrmgr are effectively 
daemons, in the sense
that they are direct child processes of xorp_rtrmgr (assuming you're 
running on a UNIX host).
