[Qemu-devel] [PATCH] do not chdir(/) in qemu-nbd

[Michael Tokarev]

When qemu-nbd becomes a daemon it calls daemon(3) with
nochdir=0, so daemon(3) changes current directory to /.
But at this time, qemu-nbd did not open any user-specified
files yet, so by changing current directory, all non-absolute
paths becomes wrong.  The solution is to pass nochdir=1 to
daemon(3) function.

This patch is applicable for -stable.
