It's not a problem of largefile support and as I'm limited in SunOS by the 
number of raw partitions on a disk (/dev/rdsk/cxtxdxs0 to /dev/rdsk/cxtxdxs7 
all used) I cannot add another 2GB buffer so I must increase the length of
CNFS buffer

[ I believe the `dd` command in INSTALL will completely zero out the 
[ buffer, resulting in INN reinitializing next time it launches.

the `dd` command in INSTALL will erase the contents of buffer but apparently 
not the information on its first length. After the dd operation the information
given by the cnfsheadconf command on buffer length is the same the first time 
you initialize this buffer (even if after you increase or decrease the buffer 
size) and apparently you can't modify its length via the -w option of 
cnfsheadconf ...

So my new questions are

1) where is contained the information of length CNFS buffers : at the head of 
buffer or in a small database where the cnfsstat and cnfsheadconf command read 
it ?

2) how erase this information ?
