What would be the point of removing everything?
What i mean is - what specifically do you want that is Fanuc and not EMC.
Do you mean you want EMC to start immediately when the computer is turned on?

I mean a system with only emc without any other installed program or service started so that the PC boots up quickly reduced to a kernel bone

Ah now I understand.
I don't believe that uninstalling everything would speed up the boot process.
hopefully someone with better knowledge will chime in.

I wrote a long reply, but it got lost, when I hit Submit. So this is the short version.

Try an install on Debian or Puppy Linux: wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#On_Debian

Try "ps -e" to find running processes and edit the init (rc.d) scripts to keep them from loading.

Try "lsmod" to find loaded modules, and "rmmod" the ones you don't need.

Look into a Flash install: wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Install_To_CompactFlash

I made a new installation on a foxconn barebone R10-D2 (Atom D510, 1 GB Mem) with Xubuntu 10.04 and the latest EMC2.
Completing the HW, and installing Xubuntu + EMC took about 4 h (without any hurry).

Boot time is < 40 sec, including BIOS, from hitting the on button to the full GUI.

I think there is not so much significant improvement possible, to justify any special Linux.
