Hi, We are using bird als a routing daemon in a meshed ethernet fabric. Bird runs on the connected hosts as well as on the network equipment to archive full layer 3 connectivity.
When we upgrade the installed packages on the Hosts, the upgrade process stops
bird, does upgrades and starts bird again.
These behavior lead to a loss of connectivity for one up to several minutes,
which make the upgrade process very disruptive.
Usually, i would expect an upgrade and a restart of the daemon after the
upgrade, which would keep the time in which the host is offline rather short.
Following questions arise:
* is this behavior intended, or is it a unintended side effect?
* did you consider this type of setups, when you implemented the upgrade
process this disruptive?
* Can you consider to fix it, easing the upgrade process in this type of setups?
In our careful evaluation, we think, using the -R parameter of dh_installinit
could ease our suffering, resulting in following patch:
