Docker: No AUFS support in Debian Kernel 3.18 (Debian "stretch")
Last modified: 2019-09-30 11:05:45 CEST
Early warning: AUFS support will be dropped in Debian Linux Kernel starting with 3.18 ( https://lists.debian.org/debian-kernel/2014/12/msg00136.html ). The new kernel will hit unstable ("stretch") shortly after the release of jessie. The docker.io version 1.5 suports overlayfs (currently in experimental). See also https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=775591 . Since the docker.io storage ("graph") drivers for AUFS and overlay(fs) use different base and sub directories, there might be a demand for a migration tool.
UCS uses overlayfs. So this problem does not effect it.
