I'm not sure that I see the rationale here.
I see three approaches:
1. With the current method, we get DEFAULT_RELEASE from
gnu/usr.bin/send-pr/Makefile, which is "<NetBSD current source date>"
for -current, and a more specific version for a release.
2. With `uname -r` at run-time, we get the kernel version of the running
kernel, which might be newer than userland. Your userland may be
out of date. A user could be requested (in the send-pr editor
buffer comments?) to indicate if userland is out of sync and
they're reporting a userland problem.
I suspect most people usually upgrade their whole system
eventually, rather than running on a -current kernel with
old userland for a long time.
Also suggesting `ident foo` output for a program (and possibly
that of any referenced shared libraries - a tool which uses
file(1), ldd(1), and ident(1) would be useful here) could be of
3. With `uname -r` at build time, we get the kernel version from that
time of build. At best this reflects the status of the send-pr
Out of these, I'd argue for `2.' as the solution. (Running system
`uname -r`, update the send-pr prompts to remind people about
kernel<->userland version skew)
(As a medium term project, we should ensure that we provide full
CVS version strings in kernel source files. I compile with full
debugging symbols (both kernel and userland), and for my kernels
I only get CVS ids for ipfilter, some wscons stuff, and one audio
driver. Something's not right there (IMHO)...)
