Interesting!

Why not use the gluon updater (that also features package signing, etc., which is sort of a hard requirement for secure autoupdates)? See the discussion at freifunk-berlin/firmware#22

In any case, the whole code should get moved to this repo, or the external code should get referenced by hash, as otherwise we don't have reproducible/secure builds.

@akira25 please look at https://github.com/freifunk-berlin/firmware-packages/blob/master/addons/freifunk-berlin-tunneldigger/Makefile#L6 for an idea how to reference to a specific commit for building this package here

As @sarumpaet mentioned, there have been some thoughts of autoupdates before --> freifunk-berlin/firmware#22

@akira25 What happened to your repo (this PR comes from)?
"Akira25 wants to merge 5 commits into freifunk-berlin:master from unknown repository" (very top of page)

[akira25]

@SvenRoederer pmlange did solve this issue by pushing the whole package to the buildbot. The package was integrated in build #1380. Therefore this PR is outdated and can be closed savely.

[pmelange]

@akira25 when you are done with your tests, please create a new pr. I look forward to this feature.

Closing with anticipation of a new PR from @akira25
