What Todd wrote is correct. In K12LTSP, access to the chroot environment on the
client is via Ctrl-Alt-F1, but must first be enabled in the lst.conf file via
the 'SCREEN02 = shell' parameter. In the lts.conf file there is a parameter
listed for enabling support for local apps, but it doesn't really work. It was
put there at the time more as a place holder for the future. The reason LTSP
4.2, on which K12LTSP was based, doesn't have a full chrooted environment is
that the idea hadn't yet come to full fruition at the time. If you need local
apps, use K12Linux/LTSP5.
