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