1 This a new implementation of a shutdown procedure. It allows
2 the system to go down graciously with informing the
3 users. This package contains 3 programs:
5 - halt = Immediately stop the system, no info to users
6 - shutdown = Inform users, close down the system properly
7 - wall = Vincent Archer's implementation of wall (Write all)
11 Shutdown and halt use a new systemcall, which I've added to
12 MM. Therefor there are several diff's which should be applied:
14 callnr.hd - New callnr for reboot(2)
15 Diff against /usr/include/minix/callnr.h.
16 Those of you using a symlink package should
17 change the number and mm/table.c into a free
18 number. I used 54, LSTAT.
19 param.hd - Defines reboot_flag as a part of the messages
20 proto.hd - Add's prototype for do_reboot()
21 table.cd - Interpretation of the systemcall to MM
22 mm.cd - I have added the do_reboot code to mm/getset.c but
23 I couldn't find a getset.c to create a useable diff :-(
24 So you can add where you want it. It is pure code, no diff.
26 Now edit log.c and search for ``host''. Change this into your
27 systemname or make it empty.
29 Shutdown and halt log their actions in /usr/adm/log, edit the
30 makefile and undefine -DLOG if you don't want this (this at the end of
31 the makefile). You can change SHUT_LOG in shutdown.c and log.c if you
32 want it in another file.
34 Then type a `make'. This will take a minute or so (13 sec. with bcc :-).
35 Remember to build a new image and update the ps_database.
37 Type `make install' to place the program's where I've got them.
38 Use them, try them and let me now if you've got problems running
41 I have tested to sources both on 16-bits and 32-bits MINIX. I have compiled
42 it with gcc, bcc and ACK, so that shouldn't really give a problem. Maybe
43 the standard MINIX-make chokes on the makefile, atleast mine did.
46 Make install does not place the man-pages somewhere. You should
