In past experience the only time I need non-ssh access is for initial
BIOS setup and MAC address extraction. Nowadays, the vendors will ship
with the BIOS settings I ask for and also provide the MAC address
externally (or I can autoextract from the initial PXE discovery
After that its PXE etc. and once I have a shell window everything is
OK. In the rare cases that I can't come to the point of a shell even
terminal access (via IMPI etc.) rarely helps since at that point a
motherboard swap or a dead HDD etc. is involved.
So, hopefully I will have very little need for IPMI (remote power
cycling is great though; those network aware power distribution stics
