It does, for me, prevent the problem on systems that I can test. I tried it under Citrix Xencenter, and the inittab entry for this console is (correctly) added. > > You mentioned a previous block which added another hvc0 (with vt100), is > that the one inside the "if [ -e $DT_ROOT/chosen/linux,stdout-path ]; > then" block? I think that one is safe. OK. I'm not really sure under what real circumstances it would be entered. My concern was that, if it is used, as /sys/bus/xen and /dev/hvc0 must both exist, two inittab lines would be produced with the same id. It strikes me that that would be in some way bad, although I haven't tried it. Dominic
