linux – How to configure PATH in cron, so that it will be set for all crons?

I have a problem where scripts called by cron have very short, safe, path: /usr/bin:/bin

I know, that I can:

  1. Change scripts to use better path
  2. in user crontab add PATH=… configuration

But I’d like to be able to tell crond that on this system all crons should be called with PATH=…

I tried putting it in /etc/crontab:

=# grep PATH /etc/crontab 

And then, for tests, I wrote:

=# cat /etc/cron.d/test 
* * * * *  test echo "$( date ) - ${PATH}" >> /tmp/test.cron.log

But logged path is still “/usr/bin:/bin”

I did restart crond, and even rebooted, just in case, but it doesn’t seem to help. What am I missing? Or is it impossible?
