Package: ltsp-client-core
Version: 5.4.2-6+deb7u1
Severity: normal

Dear Maintainer,

I have been debugging why ltsp-localapps was having no effect on my LTSP 
setup. The problem is that on the server I use /bin/zsh as my default 
shell, but this is not installed on the client. Obviously I could add 
all possible shells to the client, but this doesn't make it so 'thin'.

My fix is to add -s /bin/sh to the su command in ltsp-localappsd:
