the man snp and man watch pages neglect to mention you have to add device snp to your kernel makefile and rebuild a custom kernel, and no referenced are made from the man watch page to any document that mentions device snp.
Would it be enough just to change the first sentence to say: Watch allows the superuser to examine all data coming through a specified tty, using the snp(4) device. That at least gets the reference to snp(4) where you're more likely to see it. Or would you rather it also said something like Note that the snp(4) device is not in the default kernel so you must build a custom kernel in order to use watch(8). ? -- Ben Smithurst / ben@FreeBSD.org / PGP: 0x99392F7D
Responsible Changed From-To: freebsd-doc->dd Dima has been working recently on snp(4). It might worth adding the config(8) directive to the SYNOPSIS.
State Changed From-To: open->closed I've updated the snp(4) and watch(8) manual pages to talk about this stuff. It will be MFC'd with the rest of the snp(4) updates (probably some time before 4.5).
