I do, but I also use systemd. And GRUB2.

Seems correct.

The /run directory should be created when installing dbus; it's a tmpfs:
# mount | grep /run
tmpfs on /run type tmpfs (rw,nosuid,nodev,relatime,mode=755)
And then it's bind-mounted in /var/run. At least that's how it happens
with systemd, and that's the expected behaviour. Did you created your
initramfs with dracut?

My initramfs doesn't have a /run directory either:
# mkdir kk
# cd kk
# zcat /boot/initrd-3.2.12 | cpio -i
21514 blocks
# ls
bin dev etc init lib lib64 proc root run sbin shutdown sys
sysroot tmp usr var
However, inside /var, there is a symbolic link to /run:
# ls -l var
total 4
lrwxrwxrwx 1 root root 9 Apr 3 12:15 lock -> /run/lock
drwxr-xr-x 2 root root 4096 Apr 3 12:15 log
lrwxrwxrwx 1 root root 4 Apr 3 12:15 run -> /run
So the problem it's not the existance (or not) of the run directory, I
believe; it's the fact that it's mounted really early in the boot
process as a tmpfs. So, did you use dracut to generate your initramfs,
or did you use genkernel? Or you did it by hand?
Regards.
