[Bug 278176] Re: disk detection is real slow with some hardware (timout shell drops)

[ceg]

Concerning RAID degradiation, as RAIDs may take minutes until they come up, but regular ones are quick, this should be handled nicely:

      "NOTICE: /dev/mdX required for the root filesystem didn't get up
within the last 10 seconds.

      We continue to wait up to a total of xxx seconds complying to the ATA spec
      before attempting to start the array degraded.
      (You can lower this timeout by setting the rootdelay= parameter.)

      <countdown> seconds to go.

      Press [ESC] to stop waiting and to enter a rescue shell.

 
* This functionality is similar to and could most easily be added with upstart events (the temporary tool) mountall.
