Some host create /dev/shm as a tmpfs. Some have is as
a symlink to a location in another directory. This
change handles both cases.
The change to the sysV bootscripts now creates /dev/shm
as a separate tmpfs from /run. This makes LFS sysV and
systemd versions treat /dev/shm the same.
Otherwise, warnings are issued when changing runlevel. "ip route"
is a good test of whether network is already up. If users want to
change some config, they should use ifup/down, not the network
bootscript.
Now start and reboot should be called as "script start", and they
should be the last in their runlevel. Note that install_initd
needs to be patched for this to work; see
https://github.com/lfs-book/LSB-Tools/pull/12
Presently, there are a lot of special cases:
- runlevel 0 and 6 unconditionally run "script stop" if they
find a Kxxscript symlink. This may lead to trying to stop an
already stopped device if for example switching to runlevel 0/6
from runlevel 1. This can be fixed by stating the convention
that it is the responsability of scripts to check that the service
is running before killing it (or not running before starting it).
Still, we shouldn't try to stop a service if it was marked K in
the previous runlevel. And same for S files: we shouldn't try to
start a service that was marked S in the previous runlevel. Note
that changing runlevel is not a "reset": if a user has manually
changed the state of a daemon, this state will remain the same
upon changing runlevel if the S/K status of that dameon is
the same in both runlevels.
- Sxxscript symlinks in runlevel 0/6 are run as "script stop"
instead of the more intuitive "script start". This does not interact
well with LSB-tools (some scripts would need "Default-Start: S 0 6"
but then it is impossible to get correct "Required-Start" or
"Should-Start" fields). Furthermore, having a counter-intuitive
behavior is error prone. So now runlevel 0/6 will run "script
sart" for a Sxxscript.
Since the kernel can mount /dev if given the proper config
parameter, and we tell users to set this parameter when building
the kernel, this should be mentioned in the script
SysV only.
When stopping or rebooting the system, the network boot script is run and looks
at all the /etc/sysconfig/ifconfig.* files. Some of the devices these files
refer to may not be active or even refer to interfaces that are not defined on
the current system. This change ignores non-existant interfaces and any
interfaces that are not UP. This change also avoids bogus warning or error
error messages when the system is shutting down.
