/tmp and /var/log cleanup at boot

Post#1 by michalh » 23 Mar 2017, 09:07

Hi,

I do not want to preserve changes to(in) /var/log and /tmp dirs, how to make them fresh clean at every boot?

Thanks, Michal

Open /etc/rc.d/rc.local, create a new line in the end and put this:

Code: Select all

echo guest | sudo -S rm -rfd /var/log/*
echo guest | sudo -S rm -rfd /tmp/*
If you're not using save-changes cheatcode, then create /porteus/rootcopy/etc/rc.d/rc.local inside your Porteus bootable device and write the commands above.

Another option is to delete them at shutdown process. Use the same commands above, but inside: /etc/rc.d/rc.local_shutdown

rc.local is run before any other programs, which can write to /tmp and /var/log?

Yes, it is. But maybe it's better to use the shutdown script :)

Not so sure here. In the Web seen posts asserting that rc.local is first to be run, but after doing a diagnostic, it seems rc.S runs before rc.local.
