I've been expecting it to be default to rotate logs (or copy to ~) as it is the case with most other programs from my experience and not to have to edit an init script to get bootlogd to rotate its logs myself (only after having noticed it has grown overly). That's why I thought something might be wrong here. Thank you. Kind regards, Stefan ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

It looks like this option is missing from BOOTLOGD_OPTS above. It should be sufficient to add "-r" there. This means that you would only keep the log for the last two boots, though. Another possibility would be to have a logrotate config file for that, and keep as many logs as you want.

Hi KatolaZ,
thank you for the quick reply.

Yes, makes sense. Unfortunately this is not happening on my system.
$ ls -l /var/log/boo*
-rw-r- 1 root adm 1239019 Mär 2 11:27 /var/log/boot

I only have looked into /etc/init.d/bootlogd so far. The copied code
snippets (with line numbers) tell me that bootlogd logs
to /run/bootlog:
16 TMPLOG=/run/bootlog
20 BOOTLOGD_OPTS="-c -l $TMPLOG"
45 start-stop-daemon --start --quiet --exec $DAEMON -- \
46 $BOOTLOGD_OPTS
Then the /run/log is appended to /var/log/boot:
63 cat "$TMPLOG" >> /var/log/boot
So far so good, but nowhere /var/log/boot~ is being created, at least
not in /etc/init.d/bootlogd AFAICT.
Then there follows the mentioned code block which apparently *should*
rotate /etc/init.d/bootlogd but only if both /var/log/boot
and /var/log/boot~ already exist IIUC.
Lines 66-78:
if [ -f /var/log/boot ] && [ -f /var/log/boot~ ]
then
[ "$VERBOSE" = no ] || log_action_begin_msg "Moving boot log
file"
# bootlogd writes to boot, making backup at boot~
cd /var/log && {
chgrp adm boot || :
savelog -q -p -c 5 boot \
&& mv boot.0 boot \
&& mv boot~ boot.0
}
ES=$?
[ "$VERBOSE" = no ] || log_action_end_msg $ES
fi
Well, I can only say I probably don't understand how all of it works and
what else is involved in creating/copying /var/log/boot
to /var/log/boot~ (haven't looked into initrd) but this looks kinda
weird to me.
It's not a big issue but I'm really curious what is going wrong here.
Thanks and kind regards,
Stefan

In this way you always have the log of the current boot in /var/log/boot and the log of the previous one in /var/log/boot~. So there should be no need to rotate them.

[DNG] bootlogd: /var/log/boot does not get rotated
Good day everyone, the file /var/log/boot on my system has now grown up to more than 1.2MB. It never got rotated since I installed this system (~ June 2018). I looked into /etc/init.d/bootlogd and there's apparently some code to rotate /var/log/boot under the "stop)" clause of the "case $ACTION" construct which does a check first (line 66): if [ -f /var/log/boot ] && [ -f /var/log/boot~ ] then […] after which the code follows which is supposed to rotate /var/log/boot IIUC. /var/log/boot~ doesn't exist. It obviously never had been created and therefore /var/log/boot isn't rotated, I think. I assume this to be a bug, but as I'm not familiar with the particularities of init scripts, I'd like to ask for your opinions about that issue here.
