Now I know why I thought this. Because task-core.bb defines task packages that 
depend on X applications, any recipe that inherits from core-image will force 
a build of all of the X apps even if it doesn't intend to use them - so both 
core-image-basic and core-image-base suffer from this.  This is not really very 
good and I think we ought to be splitting up task-core to avoid this. FYI 
whilst core-image-minimal inherits from core-image it overrides IMAGE_INSTALL 
and thus doesn't use anything from task-core and therefore does not have this 
issue.

Yep, it's LSB-Core (yet another meaning of "core", sigh...)

Any opinions on this one?
