Small error in the path name?

I think the intention of the following two lines is to concat the two paths and make the test directory like <home>/<sock>

LEBench/TEST_DIR/OS_Eval.c

Lines 905 to 906 in c0663d1

 strncpy(server_addr.sun_path, home, sizeof(server_addr.sun_path) - 1); 

 strncpy(server_addr.sun_path, sock, sizeof(server_addr.sun_path) - 1);

Should this be instead:

strncpy(server_addr.sun_path, home, sizeof(server_addr.sun_path) - 1); 	
strncat(server_addr.sun_path, sock, sizeof(server_addr.sun_path) - 1);

since we want to concat the paths, instead of overwriting the path?

Thanks! Love the paper and really appreciate the enourmous amount of work you guys needed to do for that!
