Yes, I agree and in fact the patch is just now shipping

Hello Martin, so the error you are seeing is related to the chmodding
being done in sanity.bbclass, not the chmodding taking place in
oe-setup-builddir. I am adding a catch and a warning for that, as I
reproduce your setup so I can also reproduce the OSError.
Thanks.

My point was that even when such setup isn't safe from reasons other
people mentioned, the sanity.bbclass shouldn't fail with OSError
exception.

And as the issue isn't fatal for the build (I was using setup like this
for very long time and haven't noticed host-permissions-contamination
from this yet), then I would prefer just bbwarn instead of bbfatal - in
both cases is should show clear message what's wrong and what user
should do about it instead of OSError and user having to read
sanity.bbclass to see what and why failed.

Regards,

Alex

Warning informing that chmod failed is better than fatal error
preventing me to build anything in that setup with tmpfs.

     Checking may be the better approach, as warning here would do
     little more than what the current failure does (informing that
     chmod failed)

             I think you did this so that conf/ gets the right
             permissions too.
             Perhaps the best approach is:

             +chmod -st "$BUILDDIR" $BUILDDIR/conf"

         Can we add "|| bbwarn foo"

         for cases when it doesn't work for whatever reason or check the
         permissions of these 2 dirs before calling chmod?

             ?

             Cheers,
