[2022-06-13 18:05:09] \ yeah, ubuntu 22 moved stuff around [2022-06-13 18:06:41] \ ah, commented out #define res_mkquery res_mkquery and #define dn_expand dn_expand in include/resolv.h [2022-06-13 18:07:38] \ the man page has res_init and res_mkquery under a Deprecated section, so we'll see if it actually still works
