As close as I can tell from reading the code (which is to say, I am |
| 19 |
making an only slightly educated guess), the 'order' keyword in |
| 20 |
host.conf is pretty much ignored by current glibc versions. Host.conf |
| 21 |
is only consulted by the libnss_files.so module, and then only for the |
| 22 |
'multi' option. The order in nsswitch.conf is authoritative. |
| 23 |

This seems to be confirmed by a few "strace ping" attempts with |
| 25 |
various configurations. |
