  19. .SH DESCRIPTION
  20. .I Sdaoe
  21. has a few quirks because
  22. network-attached storage can't be enumerated as directly-attached storage can.
  23. The default first controller letter for AoE devices is
  24. .LR e .
  25. Each
  26. .B sdaoe
  27. device must be configured explicitly.
  28. .PP
  29. .I Addaoe
  30. packages up the
  31. .L "switch on"
  32. invocation as an
  33. .I rc
  34. script.
  35. .PP
  36. To boot from an AoE root, the
  37. .B sd
  38. device must be configured on boot by either PXE booting or
  39. booting from directly-attached storage and adding two configuration lines to
  40. .IR plan9.ini (8)
  41. for
  42. .BR aoeif ,
  43. listing the names of the Ethernet interface(s) to use,
  44. and
  45. .BI aoedev= letter !#æ/aoe/ lun.
