[Libguestfs] [PATCH nbdkit 0/2] file: Add fd=<FILE_DESCRIPTOR>

[Richard W.M. Jones]

Patch 1 looks better if you look at it with "git show -w".

This adds the ability to explicitly pass file descriptors to the file
plugin, matching a recent feature of qemu.  Actually this was already
possible on some platforms using file=/dev/fd/<N> but it seems better
to support it on all platforms[1], and make the feature and usage
explicit.

Rich.

[1] All platforms that have inheritable, numeric file descriptors, so
not Windows.
