I installed Debian jessie on a laptop with relatively new hardware, e.g. a Skylake i7-6600U processor, so I had to install the kernel and firmware-iwlwifi driver from jessie-backports. /etc/apt/sources.list has this line
deb http://ftp.us.debian.org/debian/ jessie-backports main non-free contrib
I then installed
firmware-iwlwifi=20160110-1~bpo8+1. Now that these are correctly installed, does it make sense to remove that line from /etc/apt/sources.list?
I'd like these packages to receive updates from the backports repo if any are available, but I don't want any other packages to get updates from jessie-backports. I have
APT::Default-Release "jessie"; in /etc/apt/apt.conf.d/70debconf, so that should be enough to guarantee this, right?
