name_server problem

[Leon]

Hi all,

I am having a problem with the new name_server from the l4vfs package.

I load it the name_server module with grub:

	kernel (nd)/fiasco/rmgr -sigma0 task modname "L4Linux task"
	modaddr 0x02000000
	module (nd)/fiasco/fiasco -nowait -nokdb -nofancy -serial -comspeed  
115200 -comport 1
	module (nd)/fiasco/sigma0
	module (nd)/fiasco/names
	module (nd)/fiasco/log
	module (nd)/fiasco/dm_phys
	module (nd)/fiasco/l4io --noirq
	module (nd)/fiasco/tftp -i -s 192.168.1.4
	module (nd)/fiasco/simple_ts
	module (nd)/fiasco/l4exec
	module (nd)/fiasco/l4dope --l4io
  	module (nd)/fiasco/name_server
   	module (nd)/fiasco/loader (nd)/fiasco/dope-l4linux.cfg
	vbeset 0x117

and it produces the following debug output:

	name_ser| main(): 2 ...
	 (0)/
	    file1 (56.1)
	    test3 (5)/
	        c (8)/
	        b (7)/
	        a (6)/
	    test2 (4)/
	    test1 (3)/
	    server (2)/
	    linux (1)/
	name_ser| main(): 3 ...

Q1: Where did the name_server get these names?

I wanted to test the name_server module so I ran "name_server_test" which  
always crashes with output:

I seem to get a lot of Double PF when loading my own or test programs.

Any suggestions welcome!
Thanks
