NetBSD hostname.domain 10.1 NetBSD 10.1 (GENERIC) #0: Mon Dec 16 13:08:11 UTC 2024  mkrepro%mkrepro.NetBSD.org@localhost:/usr/src/sys/arch/amd64/compile/GENERIC amd64
>Description:
When tried to install lsof via pkgin received message "The Operating System version (10.1) does not match 10.0".

The reason for high priority is I feel lsof information is needed to report a serious bug with potential to cause premature ssd or NVMe wear/failure.
>How-To-Repeat:
1) Clean install of NetBSD 10.1 via "https://cdn.netbsd.org/pub/NetBSD/NetBSD-10.1/images/NetBSD-10.1-amd64-install.img.gz";.

2) As root user install pkgin via pkg_add per:
export PKG_PATH=http://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/amd64/10.1/All
pkg_add -v pkgin

3) As root user install any package(s):
pkgin install lscpu dmidecode

4) As root user install lsof:
pkgin install lsof

5) Console result of (4):

Note I had installed xfce4 and various GUI and cli programs prior to installing lsof.  I have shortened how to repeat problem to cli based to save time in hopes my assumption how to repeat is as noted above.
