stuck in the boot process

One would think once the system boot stops at:
...
starting systems management data engine
starting dsm_sa_datamgr32d

the problem is with the systems management engine or IPMI, because it was right after that.
No, a second boot showed it just got stuck at:

...
Importing net file system (NFS)
...

and on another try:

"mount: RPC: Remote system error - No route to host"

So I had to boot into the Rescue System, mount the device where the /etc directory is on and take a look at /etc/fstab.

comment out my NFS exports in /etc/fstab

Booting worked well afterwards. Have to find out if I was just impatient (cause the NFS mounts were not available) or if it's a problem/bug.
