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: diff -ruN bird-1.6.2.old/debian/rules bird-1.6.2/debian/rules --- bird-1.6.2.old/debian/rules 2016-09-29 20:49:00.000000000 +0200 +++ bird-1.6.2/debian/rules 2016-10-11 10:27:00.717429976 +0200 @@ -69,8 +69,8 @@ dh_strip -O--dbgsym-migration='bird-dbg (<< 1.6.0-2~), bird-bgp-dbg (<< 1.6.0-2~)' override_dh_installinit: - dh_installinit --name=bird - dh_installinit --name=bird6 + dh_installinit --name=bird -R + dh_installinit --name=bird6 -R DB2MAN = /usr/share/sgml/docbook/stylesheet/xsl/nwalsh/manpages/docbook.xsl XP = xsltproc -''-nonet -''-param man.charmap.use.subset "0" Regards, Alexander Morlang ------ SysEleven GmbH Ohlauer Straße 43 10999 Berlin T +49 30 233 2012 0 F +49 30 616 7555 0 http://www.syseleven.de http://www.facebook.com/SysEleven Aktueller System-Status immer unter: http://www.twitter.com/syseleven Firmensitz: Berlin Registergericht: AG Berlin Charlottenburg, HRB 108571 B Geschäftsführer: Marc Korthaus, Jens Ihlenfeld
