Andreas, looks the problem have been existing for a long time, unfortunate there is no test
in sanity.sh to verify 'lfs setstripe -o' option, and I did not track which specific commit break this,
or it was broken even when adding first time.

The problem at least existed at ES3.x which is 2.7 series and also ES4.x which is 2.10 series.
As well as master community branch too.

Setting ost list on directory is not doable before commit 7da1d93e2320bd7e6db8062350a90a651a00f84b, since there is no place to save the ost list info. PFL's late instantiation needs to instantiate component with customized ost list during writing phase, lod_layout_component::llc_ostlist is added in that commit to make it possible. And this llc_ostlist also makes customized ost list setting upon directory possible.
