Hello Junjiro and list, Working with kernel 2.6.29 sidux-amd64, I see that aufs maintains the changes in the "cow" for a directory linked to another filesystem, I think that aufs should not mantain that,
The initrd, after mounting aufs and the root filesystem, prepares /var/run and /var/tmp with commands like that: mount -t tmpfs tmpfs /root/lnet mv /root/var/run /root/lnet ln -s /lnet/run /root/var/run ... then initializes to /root when initialized, all modifications in the files contained in the linked directory /var/run, also can be seen in "cow" Regards, Jordi Pujol ------------------------------------------------------------------------------
