All of the SuSE /etc/init.d/boot.xxx scripts execute before any services start 
to run - and thus in particular, before xend is started. You will have to 
create a simple service, put it in /etc/init.d, and put a soft link to it, 
called something like S99local, from /etc/init.d/rc5.d (for runlevel 5, etc.) 
back to /etc/init.d/local. The 99 ensures that it will be the last service 
executed.

Chkconfig probably won''t like your ''local'' service
unless you put in a header
like you will be able to see in the other init.d services.

i''m surprised if this''ll in fact be the case, as both

in the boot.local script clearly take effect @ boot.  just NOT the last cmd

in any case, np dealing with it.

thanks.

I hadn''t realized that.

Per your suggestion, the chkconfig-friendly init.d script worked perfectly.

Thanks!

xm != xenpm.  The fact that xenpm works without xend running has no
bearing on the fact that xm won''t.
