Hello Guys

can someone explain why a file read operation on /proc/net/route will 
return everything but the default gateway?
this happens only with musl and does for sure affect the command "route" 
in busybox

here a short example of this curiosity
strings does not print the default gateway.
cat does print it with default gateway

root@DD-WRT:~# strings /proc/net/route
Iface   Destination     Gateway         Flags   RefCnt  Use Metric  
Mask            MTU     Window  IRTT
