I have a /run directory. What is this and where did it come from?

wswartzendruber,

Shhh ... everyone will want one :)

It comes free with udev and or openrc. It used to be /var/run but now its needed before /var is mounted, so it was migrated to /run in tmpfs.
Its some read/write space thats available very early in the boot process.

I'm not really sure, "want" is adequate, being forced to have fits better - damn Poettering/RH :twisted:

Before /run, there was /dev/.udev. No one seemed to mind that, even though it did the same thing.

Oh, and must be nice to blame Poettering/RH for something that comes from Debian.

Really, debilian? I'm sorry, taking that back. But still, there's more than enough that weirdo is to blame for...

I think I'm getting old, too conventional maybe, but I really did not like it when I saw it first. Come on, you put stuff in my / without even asking? What about /tmp/run for instance (assuming /tmp is in tmpfs)? /tmp is a legit tenant in / after all.

They wanted to find a place, which is not prone to be on another partition, so no /{usr,var,tmp,opt}.

Seems to me that is what /etc was made for, but that is just my opinion.

/etc is not necessarily writable. Also, this is runtime data, while /etc is for static configuration. /var is the place for such data, but they needed some writable place already before /var gets mounted.
