unknown protocol icmp

[johnjelinek]

/etc/protocols is missing in the studio:

# hab pkg exec core/inetutils ping -c3 localhost
ping: unknown protocol icmp.

create /etc/protocols:

ip      0       IP              # internet protocol, pseudo protocol number
icmp    1       ICMP            # internet control message protocol
igmp    2       IGMP            # Internet Group Management

# hab pkg exec core/inetutils ping -c3 localhost

@adamhjk: ☝️ from our conversation yesterday.

If you look in $(hab pkg path core/glibc)/include/netdb.h, you'll see:

#define _PATH_PROTOCOLS        "/etc/protocols"
#define _PATH_SERVICES         "/etc/services"

The correct thing might be to have core/glibc have a dependency on core/iana-etc and patch these to point to $(pkg_path_for iana-etc)/etc/protocols, etc.

@smith I think that's the right approach

I've implemented what @smith wrote in habitat-sh/core-plans#929

:+1: on @smith’s approach.

If not done yet, it still deserves some attention IMHO. Also, the fix could be added before a refresh.
