LVM and /run

[cwr]

I notice that LVM is still using a /dev/.lvm directory, rather than /run/lvm. Is it worth
adding a Gentoo patch for this?

Upstream may have reasons for doing that. As an example, lvm has config settings to work without udev, even though it's more and more reliant on udev in the standard setup.

If they don't and it's historical, then the patch should go upstream, so that Gentoo gets it when it's been approved by them, in general. With something like LVM, you have to be conservative, since it's mission-critical for many production machines. And you have to consider all kinds of weird setups, which isn't the same as a desktop service at all. Upstream are in the best position to do that.

In summary, it probably should change, I'd just make sure you research with upstream before trying to submit a patch to Gentoo, so that your argument is well-informed, and not just "we must use /run" (which is defined to always be tmpfs, afaik.)
