The recipe link is very important, for example so I can click through and return the system (since there is no return2beaker.sh). The body of the mail even advises doing exactly that, but doesn't provide a link for it.
I (unwittingly) fixed this bug in this commit: https://git.beaker-project.org/cgit/beaker/commit/?id=1aebdf43e89891bb33ab7a2d7d69412e1ce0edb3 which will be in 19.0.
Steps to reproduce: 1. Schedule a job like this: ... <recipe> ... <task name="/distribution/install"/> <reservesys/> </recipe> 2. Wait for installation to complete and reservation e-mail to be sent Expected results: Reservation e-mail contains a link to the recipe in Beaker's web UI.
Beaker 19.0 has been released.
