OK so the result...  After about an hour fifteen minutes, lost ssh
connection.... ssh looked like this:

zorac$ sudo evtest --grab /dev/input/event2
Input driver version is 1.0.1
Input device ID: bus 0x19 vendor 0x0 product 0x1 version 0x0
Input device name: "Power Button"
Supported events:
   Event type 0 (EV_SYN)
   Event type 1 (EV_KEY)
     Event code 116 (KEY_POWER)
     Event code 143 (KEY_WAKEUP)
Properties:
Testing ... (interrupt to exit)
Connection to zorac closed by remote host.
Connection to zorac closed.
adama$

So.. On the Rawhide box log:

Apr 01 17:53:55 zorac systemd-logind[846]: Power key pressed short.
Apr 01 17:53:55 zorac systemd-logind[846]: Powering off...
Apr 01 17:53:55 zorac systemd-logind[846]: System is powering down.

So this is a bogus event since the event cannot [in theory] be delivered
to systemd, and anyway, was not logged by evtest.  This is a big problem
I think.
