Preserve $HOME in cape setup script #14

Closed zultron closed 9 years ago

zultron commented 9 years ago

See machinekit/machinekit#328

Using su clobbers the $HOME variable, which breaks X authentication and perhaps location of machinekit.ini as well.

Here, su isn't necessary, since sudo already obtains the elevated privileges needed to write to bone_capemgr.*/slots.
