// Similar to the Brew install on OSX, the Unix install happens in two steps.
// First, the system package manager installs all the binaries as root. Second,
// an autostart file needs to be written to the user's home dir, so that
// Keybase launches when that user logs in. The second step is done the first
// time the user starts Keybase.
//
// ".desktop" files and the ~/.config/autostart directory are part of the
// freedesktop.org set of standards, which the popular desktop environments
// like Gnome and KDE all support. See
// http://standards.freedesktop.org/desktop-entry-spec/latest/.
