firefox-49.0.1.tar里面的"firefox"和"firefox-bin"的区别是什么?

Debian 提供的 firefox-esr 套件中 /usr/lib/firefox-esr/firefox-bin 链接至 /usr/lib/firefox-esr/firefox-esrMike Hommey 写了：One of the reasons I'm still providing a firefox-bin executable is that historically, on unix, because of the startup script, some desktop environments would pick firefox-bin as the name of the application they need to restart (in desktop session management, most of the time). I never checked if that was still a concern, but if that is, a symlink could be helpful.
