Hi All,

I have a server that's holding downloads and sstate-cache.

I have a docker-compose file with nfs server that exposes the dowloads/sstate-cache volume.

When I mount that in my PC and set the path into DL_DIR and SSTATE_DIR, I get this error :

ERROR: grub-efi-native-2.04-r0 do_configure: Build of do_configure failed

its trying to create the file with 0600 mask. I wonder whats your
global umask set to. and perhaps the user is not same when bitbake it
running ?
The file is being created with python's tempfile function which will make it
secure. Secure in this context means 00600...

I suspect you're right that creating a file securely here with this permissions
likely can't work.
