Subject: discover: we need stderr for the BusyBox TFTP type check
X-Git-Tag: v1.0.0~273
X-Git-Url: http://git.ozlabs.org/?p=petitboot;a=commitdiff_plain;h=49f515d354d8d40e2053fe5806fea12b06bcb115;hp=33527e065d9506e05f61c020a473544123c0601b

discover: we need stderr for the BusyBox TFTP type check

Busybox tftp doesn't support -V, so prints an error to stderr. We'll
only see the Busybox identifier if we capture stderr too.
