Blacklist kernel modules

If you use rtl-sdr remember to blacklist rtl2832 modules so that the host operating system doesn't attach the devices and instead allows the devices to be claimed by the docker guest instance.

Copy and run this entire section of script at once. Note that one may need to explicitly press enter after pasting to get it to run.

sudo tee /etc/modprobe.d/blacklist-rtlsdr.conf > /dev/null <<TEXT1
# Blacklist host from loading modules for RTL-SDRs to ensure they
# are left available for the Docker guest
blacklist dvb_core
blacklist dvb_usb_rtl2832u
blacklist dvb_usb_rtl28xxu
blacklist dvb_usb_v2
blacklist r820t
blacklist rtl2830
blacklist rtl2832
blacklist rtl2832_sdr
blacklist rtl2838
blacklist rtl8192cu
blacklist rtl8xxxu
