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, and to chdir("/") after all init has been performed, before entering the main loop, -- just like a good daemon should do. This patch is applicable for -stable. Signed-Off-By: Michael Tokarev <mjt@tls.msk.ru> --- qemu-nbd.c | 8 +++++++- 1 files changed, 7 insertions(+), 1 deletions(-)
