Leave a Comment / FreeBSD, pkg / By /

You’ve seen it. A package gets installed. Some shell scripts are included. They get modified. It happens. But how do you know what has changed? I know there is a tool in pkg for this. I know there is a periodic script which uses it. Let’s go looking. In this post: FreeBSD 12.1 periodic $ cd /usr/local/etc/periodic/ $ find . | grep checksum ./security/460.pkg-checksum There it is! Looking inside, I found pkg check. […]

Case in point I started the copy-backups-to-tape process today. This appeared on the tape server: Jan 7 19:12:08 r720-01 kernel: (sa0:mps0:0:5:0): 64512-byte tape record bigger than supplied buffer Damn. Do I have a tape problem? Search results When searching for this, I found this FreeBSD Forums post from 2016 where
