[Samba] Multiple Instancies of Samba on a single System

[Gary Algier]

Yes, this works, however, you probably will want to build different
executables.  I first got it to work starting the daemons with
different configuration files, but then I had a problem with
smbpasswd: it has no config file option.  You can't make it
work differently for the different servers.  I just did multiple
configure/make runs:

     ./configure \
         --with-configdir=/etc/samba-red \
         --libdir=/etc/samba-red \
         --sharedstatedir=/var/samba-red/run \
         --localstatedir=/var/samba-red/run \
         --with-privatedir=/etc/samba-red/private \
         --with-lockdir=/var/samba-red/locks \
         ... && make &&
     make install INSTALLCMD="/bin/sh `/bin/pwd`/source/install-sh -t='s/^/red-/'" &&
     make clean

     ./configure \
         --with-configdir=/etc/samba-blue \
         --libdir=/etc/samba-blue \
         --sharedstatedir=/var/samba-blue/run \
         --localstatedir=/var/samba-blue/run \
         --with-privatedir=/etc/samba-blue/private \
         --with-lockdir=/var/samba-blue/locks \
         ... && make &&
     make install INSTALLCMD="/bin/sh `/bin/pwd`/source/install-sh -t='s/^/blue-/'" &&
     make clean

With this the smpbasswd that uses the /etc/samba-red/smb.conf file is named
"red-smbpasswd", etc.

However, to get the install to work correctly I needed to force the Makefile
to use the proper install-sh, not the in-line copies as the Makefile is
supplied.  The install-sh can do name translations.  The patch to make this
happen is:

[If these changes became part of the official code, it would be nice so we
could take advantage of the options supported by install-sh.]
