Don’t worry about NFS in the moment let’s start with SMB Kernel mount as you already have done that.
@darwindesign would most likely suggest to use path substitution but that would need some work on the command line
[HowTo] Repairing File Paths with Path Substitution
So you would do something like this
<advancedsettings>
<pathsubstitution>
<substitute>
<from>smb://192.168.0.135/</from>
<to>/mnt/192.168.0.135/</to>
</substitute>
</pathsubstitution>
</advancedsettings>
If you want to avoid doing this manual work on the command line only other way is to remove your existing sources and add them again from “Local Filesystem”
