Bug#931130: Document that local configuration for dummy and bonding modules are getting overwritten by systemd
Just stumbled upon this on upgrade to Buster on a IPsec gateway, where the dummy interface is as tunnel source IP. My solution was to let systemd-networkd manage the device by adding /etc/systemd/network/00-dummy.netdev with [NetDev] Name=dummy0 Kind=dummy and then the standard /etc/network/interfaces stanza for dummy0, followed by `systemctl restart systemd-networkd` and `ifup dummy0`. Everything is back without overriding /lib/modprobe.d/systemd.conf I thing the note should suggest the systemd-networkd solution first, as Debian adopted systemd. Thanks Petr
Bug#666021: Workaround
I've found that sysctl vm.min_free_kbytes = 65536 fixes the issue. Now testing with 16384. It seems that this is specific to PPC kernel as didn't notice this on any other machine (i386/amd64) Regards Petr -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.
