>Description:
A keen observation made by bapt@ on #bsdports when submitting the patch for
pkg_add, was the fact that the hardcoded versioning information in add/main.c
was useless in lieu of (struct uname).release's data.
We'd be losing a small potential feature in the event that ABI breakage was to
ever occur (say with the syscons utmp -> utmpx removal), but that shouldn't
occur on a regular basis and should only occur on CURRENT (where packages
should be built by the end user anyhow IMO..). Besides, if the admin knows
enough about the system he / she should be capable enough of determining
whether or not he / she should be using FreeBSD version X.Y.Z.
This eases the amount of flux with the folks in re@ and although it could have
been circumvented via the environment variable - OSRELDATE - it's just simpler
to do things this way (via UNAME_r).
If committed, this item will need an announcement on current and stable
beforehand to ensure that all affected parties are aware of the change and
update their infrastructures accordingly.
