Please find a patch to -readconfig.
On many platforms -readconfig /dev/fd/<n> can be used to read from an already opened

On platforms that do not natively provide /dev/fd/<n>
What platforms don't provide /dev/fd/<n> where fd passing makes sense?

add emulation of this by checking if the ofiginal fopen(path) failed, then IF
the path starts with /dev/fd/ then try to read the descriptorvalue and fdopen()
it.
It means that we can use -readconfig /dev/fd/<n> on all platforms. On those
that provide a /dev/fd we just open that file. On those that do not we emulate it.
