As to /home, maybe. But we're planning to (re-)harden the kernel anyway, so why bother with partial workarounds in userspace? Just in case someone runs Owl userland with a non-Owl kernel? And what do you mean by "supporting" bind mounts? Aren't they already supported (with a trivial edit to fstab)? Do you mean an installer feature? If so, I see no reason to provide it if it's just for those who would use a non-Owl kernel - that is, people who are willing to customize the system on their own. Alexander
