I've also tested on a powerpc wheezy system and amd64 unstable kvm VM. No issues found. If you would like any other scenarios testing, I'll be happy to accommodate you if possible. However, given the simple nature of the patch, I'm confident it's working correctly given that it's mounted unconditionally and will be moved onto the host if /run exists in all cases. > By the way, could you consider adding this patch to your branch: diff --git a/init b/init index 38c8a5d..cdbfe50 100755 --- a/init +++ b/init @@ -25,7 +25,7 @@ if ! mount -t devtmpfs -o mode=0755 none /dev; then fi mkdir /dev/pts mount -t devpts -o noexec,nosuid,gid=5,mode=0620 none /dev/pts || true -mount -t tmpfs -o nodev,noexec,nosuid,mode=0755 none /run +mount -t tmpfs -o "nosuid,size=20%,mode=0755" tmpfs /run mkdir /run/initramfs # Export the dpkg architecture Slightly simpler than the previous patch, but does the same job. Please note that I've now patched initscripts (http://paste.debian.net/114826/ and http://lists.alioth.debian.org/pipermail/pkg-sysvinit-devel/2011-April/004990.html) so that the filesystems mounted in the initramfs and later moved over to the root filesystem are remounted with the mount options specified in /etc/fstab (or /etc/default/tmpfs if no fstab entry exists). In consequence, it's no longer critical that the mount option defaults in the initramfs match the "real" root filesystem defaults, because they will always be applied by mountkernfs/ mountdevsubfs. So if you choose not to apply this, that's fine--it's just a "nice to have" addition; the patch as it stands without the above change is equally acceptable. Thanks for doing this.
