[Pkg-zfsonlinux-devel] Bug#992001: zfs-dkms: ZFS_META_GITREV is "unknown"

[Rich Ercolani]

Package: zfs-dkms
Version: 2.0.3-8~bpo10+1
Severity: minor

Dear Maintainer,

I was curious what versions of ZFS I had imported a given pool with, so I asked zpool history -i, and to my surprise, its log entries had "software version unknown".

Specifically (note that I believe the entries with "5000/5" were the 0.7.X behavior, as the commit to change it to report this only landed in 0.8.0):

I swapped over from backports-provided 0.8.X to 2.0.X approximately May 15th, with no change in that output.

(I also just filed a bug upstream about some releases having incorrect values in include/zfs_gitrev.h - including 2.0.3. Oops.)

A value that conveys the package version (or, at least, the upstream version, if that's not feasible) would be useful for answering things like "did this pool ever see X buggy version?" after the fact, perhaps after historical syslogs are no longer available to infer from module load.
