New Bootloader, Preliminary ELF Prebinding Patches for FreeBSD

FreeBSD Release Engineering team’s Scott Long has written a bootloader front-end script that allows one to enable/disable acpi, boot single users, etc. Elsewhere, Matthew N. Dodd has implemented per-executable ELF prebinding in FreeBSD-current. Initial performance measurements are very encouraging. Relocatable objects (executables and libraries) contain elements that require relocation before they are usable. By ‘prebinding’, much of this work can be done beforehand and speed up the actual relocation process. As a result, apps like KDE and other library happy executables take a little less time to load.
