[SOLVED] It's save to delete pkgtool log files ?

gildbg · 11-28-2021, 01:11 AM

Hello,

Today I opened the /var/log/pkgtools/removed_* directories and saw that it contains more than 20,000 files.
My question is: Can these files be deleted without prejudging the package pkgtool ?

Thanks

Yes, on -current it's safe to delete anything that pkgtools puts under /var/log. It'll recreate the directories (if need be) the next time installpkg, removepkg, or upgradepkg is run.

Thanks. Yes on current tree.

they are only important if there was a related problem and you want to analyze it.

Just don't delete anything under the /var/log/packages symlink.
That would be bad.

This is what I run before a system backup:

Code:

head -n1 $ROOT/var/lib/slackpkg/ChangeLog.txt > /tmp/_sqfsclean.$$ 2> /dev/null
if [ ! -s /tmp/_sqfsclean.$$ ]; then 
   head -n1 $ROOT/var/lib/slackpkg/current > /tmp/_sqfsclean.$$ 2> /dev/null
fi
rm -Rf $ROOT/var/{cache/packages,lib/slackpkg}/*
mv -f /tmp/_sqfsclean.$$ $ROOT/var/lib/slackpkg/current
rm -Rf $ROOT/var/log/removed_{packages,scripts}/*

For the $ROOT see the package tools and slackpkg.

Why do you want to remove these logs?

It would better to add this kind of functionality to slackpkg or pkgtool. Instead of providing home-made solutions.

To reclaim the space I should imagine.

Really ?

Code:

bash-5.1$ du -sh /var/log/pkgtools/
700K	/var/log/pkgtools/

For what it's worth ...

Code:

$ du -sh /var/log/pkgtools/
298M    /var/log/pkgtools/

But that's still nothing. Still, if someone really needs the space, it's there.

GazL · 11-28-2021, 06:18 AM

Yes, really.

Either you've already cleared it out, or there's something wrong with your du output if it's only finding 700K

Code:

# du -sh /var/log/pkgtools/
4.6M    /var/log/pkgtools/
#

And that's just 14 days worth. I use this:

Code:

# cat /etc/cron.daily/pkgtools 
#!/bin/sh
#
#  Remove old entries from pkgtools' 'removed' directories

DAYS=14  # Days to keep.

/usr/bin/find /var/log/pkgtools/removed_packages \
     /var/log/pkgtools/removed_scripts \
     /var/log/pkgtools/removed_uninstall_scripts \
     -type f -ctime +${DAYS:-28} -delete

It sounds more if you think of it as "1/4 of a GB".

As someone who started with 100K each side floppy disks, 300MB still seems like a lot to me.

300 MB does not fit with this. What are you guys doing? Updating ten times daily? Let us see contents of directories and timestamps of your logs. Logs from all updates are kept there not only recent ones? Why's that? Those with huge size of /var/log/platoon are you using slackpkg? Maybe these are slackpkg settings. You have chosen this kind of slackpkg behavior. So it doesn't remove old logs.

Edit: platoon? Wow.

Yes, it is useful to debug things which happened long time ago.
Personally, I've used cron to archive most relevant logs and discard the rest. So it's been cleared weekly.
Except for the logs symlinked to /tmp/ which is just tmpfs, cleared on shutdown/reboot.
