Strictly speaking we have to close all fds before reopening them from the image. This can be done using not yet merged nextfd syscall, but it's not yet merged :( By now just close std and 255 (bash's) descriptors. This is ugly, but I prefer to wait for the nextfd syscall. But skip the init tasks' stds becase the existing zdtm implementation uses system() in such tasks which doesn't work when all fds are closed. Signed-off-by: Pavel Emelyanov <xemul@parallels.com>
