Title:
  Dell R310 server with LSI SAS 1068E B3 requires rootdelay to boot

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  After installation, and rebooting without the install media, by
  default the administrator gets dumped to busybox.

  Typing "exit" allows the boot to continue successfully.

  Adding "rootdelay=60" to the grub configuration allows the system to
  boot automatically.

  BUG: Ubuntu Server Edition 12.04 Installer does not recognize that
  this particular controller requires additional time to initialize the
  disks and doesn't prepare a correct grub.cfg file.

  Proposed solution: add "rootdelay=60" as a default. If the server
  _does_ need the delay, then having the parameter as a default means
  that the administrator doesn't have to start searching google during
  an installation at 3AM. :)

  Since servers are typically booted and left running, (as opposed to a
  desktop system, where booting needs to be as fast as possible), a 60
  second delay on a machine that may have an uptime of 600 days seems
  like a small price to pay.

  Also, the Server Admin Guide could probably include a short section regarding this issue.
