add log file to /var/log/

[JMK8]

I have an application that writes to a log file. I create (via sudo touch) a blank log file (foobar.log) in /var/log/foobar.log. If I then create the following entry in /etc/fstab...

Code: Select all

tmpfs                                          /var/log           tmpfs   size=50M,nodev,nosuid        0       2

...reboot and then look in /var/log/ I cannot see foobar.log if I..

Code: Select all

cat /var/log

All the other log files are visible.

I cannot compute

You're mounting a tmpfs over /var/log which means any existing files in /var/log such as foobar.log will be hidden and you can't access them. The other files still exists because rsyslog recreates them.

I didn't realize rsyslog was doing that. Something new learned. Thanks for the pointer.
