We have always tried to avoid trying to detect hardware and add kernel
parameters based on the results; it is problematic for a variety of
reasons.  Can't the kernel notice that it has no RTC devices and behave
as if 'fixrtc' were set?  It seems that the kernel should be in the best
position to make this kind of decision.

Title:
  debian install fails to add fixrtc to systems that do not have a
  battery backed RTC (arm)

Status in “debian-installer” package in Ubuntu:
  Incomplete

Bug description:
  Most arm development systems (beagle, panda, etc) do not have a
  battery backed RTC.  The RTC gets set by looking at the timestamp of
  the rootfs partition, but only if "fixrtc" is added to the kernel
  cmdline.  Without this addition, the system may hang while doing a
  filesystem check due to timestamps being in the future.
