The unit names with "@" in the name are such templated units. The files on disk are name foo@.service, and at runtime you can then instantiate them as foo@bar.service, foo@waldo.service and so on. The "foo" in this scheme is the template name, while bar/waldo/... is the instance id. In my proposal below I suggested using one template and then instantiate them once for each failed unit, using the faile unit's name as the instance id. > > -----Original Message----- > > From: Lennart Poettering [mailto:lenn...@poettering.net] > > Sent: Monday, December 01, 2014 5:46 PM > > To: Nekrasov, Alexander > > Cc: systemd-devel@lists.freedesktop.org > > Subject: Re: [systemd-devel] reacting to unit failures (OnFailure) > > > > On Mon, 01.12.14 17:10, Nekrasov, Alexander (alexander.nekra...@emc.com) > > wrote: > > > > > Hello, > > > > > > While converting from Upstart to SystemD, came upon this issue.
