Debian Jessie and issues with IPv6 and Time Machine

I upgraded my little basement Mac Mini workhorse from Debian Wheezy to Jessie the other day. Fixing a couple breakages that resulted whose solutions were a little hard to find might be useful for someone.
  • SpamAssassin started passing a lot more spam through to my inbox. That ended up being an issue with addresses for services being contacted by spamd no long resolving via named, which in turn turned out to to be IPv6 related. Disabling IPv6 fixed that: echo "net.ipv6.conf.all.disable_ipv6 = 1" >> /etc/sysctl.conf; sysctl -p
  • Related? Performing Time Machine backups to that machine's netatalk provided volumes began failing. A look in the logs showed afpd ... sys_getextattr_size: error: Permission denied errors logged. Adding ea:sys to the corresponding mount point in /etc/netatalk/AppleVolumes.default and a systemctl restart netatalk fixed that.
Thus ends a small bus man's holiday exercise.
