/sbin/bootlogd

Hello,
isn't there nobody, whom can help?
How could it disappear or another possibility during the installation process were a error.
I don't know, but one is clear the /etc/init.d/bootlogd is still there but /sbin/bootlogd isn't.

Is there under Ubuntu another way to save the earlier boot messages, the boot
parameter earlyprintk=vga,keep doesn't work. The kernel crashed.

Please have a look to my request #2690. I figured out some details and wrote them there.

Thanks in advance,
                                  Mr Canis

/etc/init.d/bootlogd is part of the 'initscripts' package and /sbin/bootlogd is in 'sysvinit'. However, quite happily, there's a dependence between both packages, so you should'nt have one without the other.

Can you check if you have both installed? Which version of Ubuntu are you using?

Hello Antoine Delvaux,
thanks for your answer.
I'm using Ubuntu 6.10 edgy with all upgrades and the package
'initscripts' are installed but 'sysvinit' are not. In the
dependencies of 'initscripts' is written that it conflicts with
'sysvinit'.
The programm /sbin/bootlogd doesn't exist on my system.

Thanks in advance.

Well, my observations was based on 6.06 Dapper but should still be true on Edgy. It's the sysvinit source package which creates the two binary packages. I guess both should be installed.

For Edgy: https://launchpad.net/ubuntu/+source/sysvinit/2.86.ds1-14.1ubuntu16

For Dapper: https://launchpad.net/ubuntu/+source/sysvinit/2.86.ds1-6ubuntu32

Not sure why they're not. If you try to install the package named 'sysvinit', what happens?

Hello Antoine Delvaux,
that's the answer from synaptic:

To be removed
   startup-tasks
   system-services
   ubuntu-minimal
   upstart
   upstart-compat-sysv
   upstart-logd

I think to install 'sysvinit' isn't a good idea. There must be another
reason why bootlogd isn't installed in edgy.
I have an other laptop (Toshiba Tecra 8100) with edgy. On this
installation bootlogd isn't installed too, but all boot messages appear
in dmesg.
It's a little bit strange.

Mr Canis,

Indeed, having those packages being removed is not a good thing. However I still don't understand how you have initscripts installed without sysvinit.

Which package version of initscripts is installed? (run 'apt-cache showpkg initscripts') And which version of sysvinit are you trying to install? An output of 'apt-get -s install sysvinit' (which simulates the installation of sysvinit) could help.

Thanks.

BTW, bootlogd purposes isn't to make boot messages available under the 'dmesg' command or /var/log/dmesg file but to save console boot messages (what is normaly printed on the console screen) in /var/log/boot.

It's the duty of /etc/init.d/bootmisc.sh (part of initscripts package) to store the 'dmesg' boot time output into /var/log/dmesg. The dmesg command returns what is currently stored in the kernel ring buffer. This buffer is of fixed size and so is regularily overwritten (it is not only used at boot time). That's why bootmisc.sh is run during boot, to save those messages in a file before they get overwritten.

Thus, even if both are created at boot time, output of /var/log/boot and /var/log/dmesg should be quite different.

Hello Antoine Delvaux,
thanks for the brief description, but exactly the earliest boot messages are missing. The dmesg output begins with the message from hda_intel driver and in /var/log/boot the first entry is " Mar 20 05:44:23 rcS: * Files under mount point '/var/run' will be hidden. "

below the output from apt-cache and apt-get.

Ok, I now understand the conflict, it's because of the new 'upstart' package which is replacing the sysvinit, see https://wiki.ubuntu.com/ReplacementInit

As it is work in progress (full replacement is to be due for Festy), a replacement for sysvinit is included in upstart, but not yet a replacement for initscripts. This does explain why you don't have the /sbin/bootlogd (as it is part of sysvinit) and why you still have /etc/default/bootlogd and it's starting script (as those are part of initscripts).

I guess either bootlogd is to be included in upstart or the configuration files needs to be suppressed. I'll fill a small bug report with that.

However, as you can see from your /var/log/boot message file, another logging daemon is now in use, it's called 'logd' and is part of 'upstart'. This is really the bootlogd replacement. As this one, it's only capturing start jobs output directed to the console and so doesn't print kernel boot messages.

The kernel boot messages should be saved in your /var/log/dmesg, but if you cannot see all of them in there, that's another story.

Hello Antonie Delvaux,

does it mean, that the package "sysvinit" can do all the thing what the new package "upstart" does?
i have this question because there is still no /sbin/bootlogd by feisty, i'd like to log the boot, but without the /sbin/bootlogd, i can do nothing...

Thanks

qiuye

The aim is indeed to replace sysvinit completely, but the transition is not complete now I think.

Hello, I'm having the same problem too, I would very much want to get this bootlogd output, but it's not working. Is there any possibility to do some kind of workaround, like compiling and installing bootlogd manually or something? Does anyone know how to do that? I would be very happy if someone could help med with this, because I'm trying to debug a problem where the system sometimes hangs at boot.

Oh, I forgot to mention, I am using Ubuntu 7.10.

Hello,
I use following kernel parameter:

ignore_loglevel log_buf_len=16M

And of course without quiet splash!

More about kernel parameter are in

a) /usr/share/doc/linux-doc-2.6.22/Documentation/kernel-parameters.txt.gz
b) /usr/src/linux/Documentation/kernel-parameter.txt

Hope it helps.

Mr Canis

Thanks for the suggestion, I'll try it out.

Hello,
good luck ;-)

Mr Canis

Hello,
I close this support ticket because the problem isn't bootlogd but logd and the new upstart concept.
