>Category: bin
>Synopsis: cannot submit at jobs from within an at job
>Confidential: no
>Severity: serious
>Priority: medium
>Responsible: freebsd-bugs
>State: open
>Class: sw-bug

>Release: FreeBSD 2.2
>Environment:
2.1.x and 2.2
>Description:
You cannot submit an at job from within an at job, since the submitted
job will have the wrong mail address, and atrun will reject it. The
comments suggest that the code in question (see below) is a hangover
from an earlier day, and no longer appropriate.
>How-To-Repeat:
Have an at job that submits itself. Run the at job as someone other
than root. The submitted job will not run.
