Subject: [PATCH 06/12] sysv-generator: add (back) support for SysV scripts for
|
|
the early boot
|
|
|
|
For the record, the upstream support was removed by commit
|
|
3cdebc217c42c8529086f2965319b6a48eaaeabe.
|
|
|
|
The sysv-generator has some weirdos: for example a service at the rc0
|
|
runlevel won't be started during shutdown since it will get both
|
|
"WantedBy=poweroff.target" and "Conflicts=shutdown.target".
|
|
|
|
Anyways what's the current patch implements the following:
|
|
|
|
- a symlink /etc/init.d/boot.d/S??boot.foo will add
|
|
"WantedBy/Before=sysinit.target" constraints and make sure that the
|
|
default dependencies added by systemd are turned off.
|
|
|
|
- a symlink /etc/init.d/boot.d/K??boot.foo will add
|
|
"Conflicts/Before=shutdown.target" so "foo" service will be stopped
|
|
like any other regular services. If this symlink is not installed
|
|
however, "foo" will be stopped lately during the systemd killing
|
|
spree.
|
|
|
|
This is a forward-port of commit 29db8537e1ca10796797d9854d1 in SP1.
|
|
|
|
[Since v232]
|
|
|
|
Support for S* symlinks in runlevel 0 or 6 has been completely and silently
|
|
removed by 788d2b088b13a2444b9eb2ea82c0cc57d9f0980f. Since it was already
|
|
broken as pointed out above, this probably wasn't really used and therefore
|
|
no one will really care. So let's drop it too.
|
|
|
|
However this has the side effect to make the support of early sysv scripts more
|
|
difficult. To make things easy, the support of K* symlinks in boot.d/ has been
|
|
removed too: this is probably not used (anymore) (at least intentionally).
|
|
|
|
The consequence is that early sysv services are stopped during shutdown at
|
|
the same time as 'normal' services.
