The first shell executes a single line of shell commands, namely to change directory and run another shell.
The second shell runs as the "normal" interactive shell. 
Net effect - looks like the shell has started in a different directory. Admittedly a bit hacky, having two shells running for no good reason, but 
it does the job. I'm not sure if shells are very expensive in terms of memory. If not, then its a bit kludgey, but otherwise its ok.

There's bound to be... anyone got any idea?
I saw another posting to the list where the cd gets written to a file then the login script looks for the file and changes to that dir... that's an 
option.
