Bug with fixit live 8.0 memstick.img running on F1 after MBR

[Julian H. Stacey]

Hi Hackers,
Bug found with fixit live 8.0 memstick.img running on F1 after MBR :

First I checked my PC BIOS boots OK:
  I copied 8.0-RELEASE-i386-memstick.img to a raw 2G USB stick, it boots
  fine, & one can go into fixit menu, using image on stick

Next
  I fdisk partitioned an 8G stick & copied 8.0-RELEASE-i386-memstick.img
  to F1 (da0s1), set F1 active, booted OK, went into fixit, selected
  USB stick for the live media, & it failed to find a USB media.

  (The live command prompt on F4 wasn't much use, no ls yet.)

  I tried telling it to install to F2 (6.5 G ufs), using files from
  local FS on stick, (I told it path 8.0-RELEASE ) but on 2 attempts,
  it couldnt find where to install to get bins from.

  I since confirmed those files are there on F1 8.0-RELEASE/ , see below.

Conclusion:
  Would be nice if others tried too, to tell if it's my mistake or a bug.
  WOrth doing as it also sets you up ready with a stick that can rescue/
  fixit + has enough space for other file systemes with your own
  personal /usr/local inc. X, ready for eg testing laptops in shops.

  I since mounted my 8G stick on a normal 8.0 PC & installed F2
  from /usr/src & /usr/local from hard disc. I have another 4G I
  could test with MBR, but testing here is disruptive as only my
  main machine has boot- off- USB functionality).

I mounted both sticks later to document what I was using:

2G stick with no MBR, (`dangerously dedicated', that worked OK:
  ls -l /devusb/red -> /dev/da0a
