Yes, but at least the "running a different kernel" case is currently the relatively rare one. >> and it also makes >> the 'what do you with the live image' case a lot more complex. > > I'd just go with PAE here. Can't do so -- the live image is definitely used on a lot of hardware that isn't PAE capable. Many/most Pentium M's didn't support it, the OLPC doesn't[1].

Want to write code for syslinux and grub to do the auto-choosing? Then we also have to figure out a way to shoe-horn another 50 MB of stuff into the already full live image Jeremy _______________________________________________ Fedora-kernel-list mailing list Fedora-kernel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-kernel-list
