`raspbian.raspberrypi.com` vs `deb.debian.org` in `sources.list` #726

Closed bradisbell closed 9 months ago

bradisbell commented 9 months ago

In the arm64 branch of stage0/00-configure-apt-files/sources.list, deb.debian.org is referenced:

deb http://deb.debian.org/debian RELEASE main contrib non-free non-free-firmware
deb http://deb.debian.org/debian-security/ RELEASE-security main contrib non-free non-free-firmware
deb http://deb.debian.org/debian RELEASE-updates main contrib non-free non-free-firmware
# Uncomment deb-src lines below then 'apt-get update' to enable 'apt-get source'
#deb-src http://deb.debian.org/debian RELEASE main contrib non-free non-free-firmware
#deb-src http://deb.debian.org/debian-security/ RELEASE-security main contrib non-free non-free-firmware
#deb-src http://deb.debian.org/debian RELEASE-updates main contrib non-free non-free-firmware

In the master branch, it's raspbian.reaspberrypi.com:

deb [ arch=armhf ] http://raspbian.raspberrypi.com/raspbian/ RELEASE main contrib non-free rpi
# Uncomment line below then 'apt-get update' to enable 'apt-get source'
#deb-src http://raspbian.raspberrypi.com/raspbian/ RELEASE main contrib non-free rpi

Is there a reason for this difference? Are armhf builds not available on deb.debian.org?

I ask because the performance of the Fastly-hosted deb.debian.org is much better than that of raspbian.raspberrypi.com. We found that moving to deb.debian.org cut our Pi image building time about in half. Perhaps the armhf users can make use of the Fastly-hosted Debian mirror as well, if possible.

The difference is that one would build an image with a Raspbian base, suitable for armv6 pi models, while the other would use Debian and only work on armv7 and higher.

@XECDesign That's only due to this tag [ arch=armhf ] though, right? Or is there something different about what's hosted on raspbian.raspberrypi.com beyond it just missing >=armv7 binaries? Or, is it that deb.debian.org doesn't host armv6 binaries?

XECDesign commented 9 months ago

Debian's armhf is armv7 only. There's armel for armv6, but it's soft fp only.

You can read a bit about what Raspbian is and how it differs from Debian here.
