15.0 - rc.conf ignores a setting

[infoomatic]

Hi,

I have a pkgbase 15.0 which ignores the new setting
precious_machine="YES" in rc.conf. It does not happen on non-pkgbase
15.0 systems. What could be the problem?

Regards,

Robert

What command and flags are you using to try shutdown the system?

Does the behavior change if you manually create the /var/run/noshutdown
file?

E.g. when I 'touch /var/run/noshutdown' on a 15.0 test VM it properly
prevents shutdown with the message "Shutdown cannot be done,
/var/run/noshutdown is present".

I'm guessing your system's shutdown binary doesn't have the noshutdown
function somehow -- is your system from an upgrade or a fresh install?

A quick way to check the binary itself:

$ strings /sbin/shutdown | grep noshutdown
Shutdown cannot be done, /var/run/noshutdown is present
/var/run/noshutdown

If you don't see that sort of output, I think that shows why you have
the problem, but not necessarily how it got that way.

Cheers,
sr.

I have verified that manually touching that file works. However, at boot
time it seems like /var/run/noshutdown is not being created.

I have FreeBSD-set-kernels and FreeBSD-set-minimal-jail installed.

However, I installed FreeBSD-set-base, which installed the packages in
the list below [1]. Now it works, any ideas what package could have been
missing?

Thanks and regards,

Robert

FreeBSD-rc is missing. It is required by FreeBSD-set-minimal which is
required by FreeBSD-set-base, so it should be there, but it is not in
your list. I'm not sure how you managed to boot without it, but never
mind that. Please try `pkg check -ad`.

Thanks for the response. 'pkg check -ad' prints 'Checking all packages:
100%'

I uninstalled FreeBSD-set-base plus the sets that were pulled in and did
autoremove the packages. Now I have FreeBSD-set-kernels,
FreeBSD-set-minimal, FreeBSD-set-minimal-jail and also the package
FreeBSD-rc is installed. However, the setting is ignored again at
startup - /var/run/noshutdown is not being created.

Robert

I didn't ask you to do any of this. Just confirming that you already
had FreeBSD-rc (despite it being missing fromt the list that you posted
earlier) would have sufficed.

I took a closer look at the script that creates it. Turns out, it can't
possibly work as written. I wonder if it was ever tested?

% rcorder /etc/rc.d/* |& grep -A1 noshutdown
/etc/rc.d/noshutdown
/etc/rc.d/cleanvar

Take a wild guess what the cleanvar script does...

We don't run rc scripts twice. We call run_init_scripts twice, but it
keeps track of which scripts it's already run and doesn't run them again
the second time.

Now, please: 

pkg iinfo FreeBSD-console-tools

Is the FreeBSD-console-tools package still installed?
