So, seeing as settling on a way to determine stdout still up in the air, it probably makes sense to condense that code down to a single authoritative function so that changes in this area are contained in one place. For now, I'll stick with decoding linux,stdout-path and on Sparc decoding the ihandle with the expectation that there will be further refinements to be made. g. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
