running the 'id' command inside the sstate_create_package
function shows that this funcion run inside the pseudo:
uid=0(root) gid=0(root) groups=0(root)
The check for touch files [ ! -w ${SSTATE_PKG} ]
will always return true and the touch can fail
when the real user don't have permission or
in readonly filesystem.
As the documentation refers, the file test operator "-w"
check if the file has write permission (for the user running the test).
We can avoid this test running the touch and mask any return errors
that we have.
