[Bug 883663] [NEW] Silly redesign of mount tmpfs over /run prevents machine from booting properly

[Hadmut Danisch]

Public bug reported:

Hi,

I just upgraded a machine (not the one I am writing this bug report on)
to ubuntu oneiric. The machine simply can't configure its network
interfaces anymore, since ifup from package ifupdown needs to put its
state into /var/run/network/ifstate

Unfortunately the directory /var/run/network does not exist at boot time
because the oneiric initrd code mounts a fresh tmpfs over /run and links
/var/run into this freshly created file system, thus causing the missing
/var/run/network and so keeping ifup from work.


As I saw there are plenty of reports for bugs caused by putting a tmpfs onto /run, which is, btw., a waste of RAM.


How can someone replace /var/run with a tmpfs created freshly at boot time, thus deleting all directory structures under /var/run? This is broken by design (and obviously breaks so many functions). 

How can you do that? Who made this decision?
