Maintainer: me
Compile tested: not yet
Run tested: no

Description:

To prevent birdc writing its history file to /root, causing flash wear,
apply a patch that moves the history file to /var/tmp instead.

Fixes #1137.

what is needed for testing?

apk add /tmp/bird2c-2.17.2-r2.apk --allow-untrusted
(1/1) Upgrading bird2c (2.17.2-r1 -> 2.17.2-r2)
bird2c-2.17.2-r2.post-upgrade: Executing script...
OK: 29 MiB in 178 packages

That looks good as far as testing is concerned, thanks! I just need to figure out why the CI complains about the patch; I take it you didn't have any issues building the package?

Just do a make package/bird2/refresh, that should fix it?
