According to: https://hydra.gnu.org/eval/109381?filter=icecat#tabs-removed
the jobs for icecat on armhf and mips64el were removed in evaluation 109381 (corresponding to commit 663d5b5), but were present in the previous evaluation 109380 (commit cd65d60). Can anyone tell me why this happened? I guess that the 'supported-systems' field of some package that 'icecat' depends on was recently changed, but I was unable to find anything obvious by grepping through the output of "git log -p". Debian includes Firefox packages for 'armhf' and 'mips64el', so it's obviously possible to get it working on those platforms. I find it disturbing that we seem to be in the habit of removing non-Intel systems from 'supported-systems' fields in packages that other distros are able to get working on non-Intel. These are bugs to be fixed, not swept under the rug to get them out of sight. Mark
