I also endorse such a change.
There is a significant gap in recoding removable media activity (see
https://bugzilla.redhat.com/show_bug.cgi?id=967241) and the on_mount could go a
reasonable way to address this, including making use of the
NETLUNK_KOBJECT_UEVENTnetlink group or /sys/block polling to assist with device
discovery.
Secondly, being able to react to a login/logout event also opens up interesting
opportunity for targetedevent generation.
That said, I believe that Juro Hlista did some work on this back around 2010. He did
this via a plugin. His solutionwas a little more generic. Should we be looking at
that as a solution as well? One element I do remember from hiswork, was that there
was a potential gap in the time to react to a trigger firing and the result was that
one was notguaranteed to implement the new rules immediately. I assume to treat this
gap, the rules could be preloaded and the 'trigger' action could just move the
'dormant' rules, already in core, to the 'active' list.
I was going to say, this one feels like there are a set of rules that
should just be present from the get-go and not dynamic. If we already
know what we are looking for (monitor a specific user, or monitor a
specific device) then just add those rules to the permenent set.
This makes it easier to lock things down too.
