Indeed: $SRC/cmd/fs.d/autofs/autod_main.c has this:
178 #ifndef DEBUG
179 pid = fork();
180 if (pid < 0) {
181 perror("cannot fork");
182 exit(1);
183 }
184 if (pid)
185 exit(0);
186 #endif
Why that's ifndef'ed, I don't know. Also, there's this oddity in
automount.h:
#ifndef _REENTRANT
#define fork1 vfork
#define rpc_control(a, b) 1
#endif
And, further, automountd forks again:
217 pid = fork1();
218 if (pid < 0) {
...
230 } else if (pid > 0) {
231 /* this is the door server process */
232 automountd_wait_for_cleanup(pid);
233 }
where automountd_wait_for_cleanup() just waits for the child and then
exits. The parent there seems to exist to serve door requests on
did_fork_exec and did_exec_map, but why must that be done in a separate
process when both processes run with the same credentials and
privileges?
Very odd.
