Moving local settings for pg_hba.conf and postgresql.conf out of PGDATA

One of the configuration aspects of FreeBSD I have long liked is the concept of default values which are overridden by the user. For example, /etc/defaults/rc.conf (see The /etc directory). The default values in this file can be overridden by the user with their preferred values in /etc/rc.conf (or /etc/rc.conf.local, and other locations if you

OK, we got a Time Machine on ZFS on FreeBSD. So what. Can we restore from it?

I have written recently about creating a ZFS-based Time Machine on FreeBSD. Yesterday, I did my first restore from this instance. Surprise. It worked. Please move along. Nothing to see here. Just photos. The motivation: I’m replacing one MacBook with another. Some details here on Twitter. Edit – 2024-02-22 After I messed up when renaming

I will provide only the jail configuration, and not any file system configuration. That is left for you. I think these links might be most helpful: Using poudriere to

Clearing-out multiple drives concurrently – while Watching Fargo Season 5

It is time to let the knew server go. It has gone through multiple upgrades, new drives, new boards, and new chassis. It has been replaced by r730-03. Before I let it go, I want to clear off the drives. By that I mean: I did this by booting the host using mfBSD (a lovely
