I had an actual kernel patch in one linus -rc kernel to export smbios table as a sysfs entry. The backlash generated prompted me to withdraw the patch. AFAICT, userspace should be able to do this itself. SUID is one way. I'm currently looking at docs for HAL and DBUS as another. I'm leaning towards HAL/DBUS, but they are semi complex and I'll need some help making sure I get it right. -- Michael -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
