Subject: question about /dev/root symlink

All,

I am part of the team that maintains udev on gentoo.

This bug [1] has prompted me to ask a couple of questions about the
/dev/root symbolic link.

According to upstream udev, we should not use this at all and if tools
are relying on it they should be fixed to not do so.

Does the kernel create this symbolic link in devtmpfs as suggested by
[2] and [3]? If not, should I be writing custom udev helpers to create
it?

Thanks much for your time,

William
