Calling daemon() after proc_init() will detach the children from the
parent process. Also return errno if daemon fails.

See ps auxf:

root     70446  0.0  0.1  1964  2360 ??  Ip     Wed11PM    0:00.02 - /usr/sbin/httpd
www      22440  0.0  0.1  2192  4704 ??  Ipc    Wed11PM    0:02.88 - httpd: server (httpd)
www      27514  0.0  0.1  1664  2940 ??  Ipc    Wed11PM    0:00.02 - httpd: logger (httpd)

which should be:

root     43158  0.0  0.1  1964  2344 ??  Ip      6:58PM    0:00.01 - /usr/sbin/httpd
www      64572  0.0  0.1  1932  4280 ??  Ipc     6:58PM    0:00.01 |-- httpd: server (h
www      16700  0.0  0.1  1660  2804 ??  Ipc     6:58PM    0:00.01 `-- httpd: logger (h

patch syncs what iked does.

ok?
