I think you feel more strongly about the topic than it warrants it -
"almost every" is not "every" and glabel is technically a slicer just
like gpart - you wouldn't like gpart to announce as it creates da0s1a,
da0s1b, da0s1c, etc.? Besides, the trend is toward reducing the amount
of generic (redundant, repeatable) information on boot. :)
What could be possibly more useful is to create a framework that would
output only "diff" messages - i.e. that shows that I had da0s1a or
ufs/mylabel when I booted last time, and I suddenly lost it now. But
this is non-trivial for many reasons, including how and where to store
the information and what to do with hot-plug devices. Maybe devd could
take care of all these announcements?

I was thinking about the "ls /dev" case. What other thing would be a
concern in the number of entries in what's essentially a very light
weight memory file system whose content are nodes of several bytes in
size (less than 100 bytes if I count them correctly, +vnodes, labels,
