[pocket-linux] trouble understanding 8.3.2 ...

[Rainer]

hello,

things have been going pretty smoothly since i ironed out that 
'ramdisk=4096' but i'm having trouble comprehending the instructions in 
8.3.2! the last command creates /dev/null in the usual way - i get 
that.  i fail to fathom the 4 previous 'ln -s ...' commands. it looks 
like i'm creating a soft link from my build system /proc/self/fd  > 
/staging/* ???  is all that stuff i'm supposed to be reading coming 
back to haunt me? thanks.
