[arch-general] startup messages gone

[Martti Kühne]

hey

this quick and minimalistic patch [1] to rc.{sysinit,single,multi}
here works to capture almost the complete boot output in per-script
manner in /bootlog. don't forget to mkdir /bootlog when you apply it.
use less -r to read them, and don't be irritated, it will change the
results for right-aligned output (like [DONE]). dmesg errors aren't
recorded, but those go to /var/log/dmesg.log anyway.
