I've seen the man page :) AFAIK, running it as a daemon is preferable,
and I've always run it that way. If you had read further up the man
page you would have found:
"Operating the server as a daemon is the recommended way of running
smbd for servers that provide more than casual use file and print
services. This switch is assumed if smbd is executed on the command
line of a shell."

The problem with needed to restart nmbd manually (or via an additional
script) that I alluded is one reason. Choosing to not run smbd as a
daemon seems to be mistake in one way or another - you can set daemon
or inetd mode in /etc/default/samba but the smbd.conf upstart script
is hardcoded to run "smbd -F" and just as oddly the nmbd.conf script
is hardcoded to run "nmbd -D", both ignoring the setting in
And I have seen reported instances of Samba issues on Ubuntu being
resolved by avoiding the distro packages and compiling from source.
