Is it feasible to mount /run on say /dev/shm/run
And regarding the tmpfs (RAM disk) , you can use /dev/shm.

# cat /dev/shm/key

It is not advisable to store larger amounts of data there, but an
encryption key should be fine.

Ok, we're getting closer.
- Run cygserver-config as an administrator.
- Do "net start cygserver"
That will provide shared memory capabilities. Then try this:

Shared memory segment exists - opening as client
Done...

I can see two options:
1. You create a RAM disk and the contents will obviously be gone when
the system reboots or crashes.
2. You encrypt the data with a ephemeral key that will be lost on reboot
(e.g., kept in shared memory). When the system comes up and finds itself
unable to read the data,

I need to store some data (a few kB) non-persistant.
On a real UNIX I would use /var/run, because after a shutdown all its
content is lost.
But on cygwin /var/run is stored on disk.
I cannot use an environment variable, because different processes need to
read/write the data.
/proc is non-persist
POSIX [1] specifies that the return value of the functions ilogbf(), ilogb(),
ilogbl() for a zero argument should all be the same, namely FP_ILOGB0.

In Cygwin 2.9, the value of ilogbl(0.0L) is not right.
