1 | # Replaces traditional overdesigned shutdown mechanism. | ||
2 | # | ||
3 | # No communication with init is necessary: | ||
4 | # just ask all processes to exit. | ||
5 | # Then unmount everything. Then reboot or power off. | ||
6 | |||
7 | # Install /sbin/ symlinks named halt, reboot, poweroff | ||
8 | # (and also possibly shutdown) to e.g. | ||
9 | # /app/shutdown-1.0/script/shutdown: | ||
10 | # | ||
11 | ln -s /app/shutdown-1.0/script/shutdown /sbin/halt | ||
12 | ln -s /app/shutdown-1.0/script/shutdown /sbin/reboot | ||
13 | ln -s /app/shutdown-1.0/script/shutdown /sbin/poweroff | ||

15 | # shutdown spawns do_shutdown in new session, redirected to /dev/null, | ||
16 | # tells user that shutdown is in progress, and sleeps | ||
17 | # (for cosmetic reasons: do not confuse user by letting him | ||
18 | # type more commands in this terminal). | ||
19 | # | ||
20 | # do_shutdown tries to switch to a VT console. | ||
21 | # Then, (only if -r) it spawns a hardshutdown child, to reboot | ||
22 | # unconditionally in 30 seconds if something later goes seriously bad. | ||
23 | # Then it runs stop_tasks, writing to /var/log/reboot/YYYYMMDDhhmmss.log, | ||
24 | # then it runs stop_storage. | ||
25 | # Then it commands kernel to halt/reboot/poweroff, if requested. | ||
26 | # Then it sleeps forever. | ||
27 | # | ||
28 | # Build the hardshutdown binary: | ||
29 | # | ||
30 | cd script && ./hardshutdown.make.sh | ||
