I want a list of all the children of a #ZFS filesystem. I'm using:

$ zfs list -Hr -o name -d 1 foo/bar
foo/bar
foo/bar/a
foo/bar/b

I don't want the parent in that list (i.e. foo/bar). Can `zfs list` do that?

If not, I can use grep to get rid of `foo/bar`.

The output I want is:
foo/bar/a
foo/bar/b

To initiate processing of git commits in the #FreeBSD ports tree, the last remaining change is to this line in /usr/local/etc/freshports.org/config.sh:

REPOS_TO_CHECK_GIT="doc src"

But first, I have this bagel in front of me.

#FreshPorts

I'll work on configuring FreshPorts for the new git ports tree at about 1600 UTC. Lunch time.

Updating an existing mosquitto installation from 1.x to 2.x?

There are changes to pid file, certificate, and configuration file permissions.

Today someone mentioned creating a cron job. That reminded me of:

* when thinking crontab, consider periodic
* when thinking mkdir, consider zfs create

3 days later, this question

"Interesting idea. With standard newsyslog.conf on #FreeBSD, how can you rotate a log file daily, but only if it's non-empty?"

results in a new feature:

"a new flag, 'E', that prevents newsyslog(8) from rotating the empty log files."

I did others too. One completed in:

Let's try this:

Friends do not let friends use btrfs. In a redundant file system, I want to at least do a mirror of my OS boot drives. If one of them dies, I want my system to continue to operate.

I'm told btrfs won't boot such a system. By design.

Please tell me this is not so.

Blog post about how to register a package without installing the package, thus preventing the package from being installed.

What?

Imagine you have a dev system, and you want to avoid accidentally installing the package for the code you are working on.

After an afternoon of volunteering (thanks $WORK) at a vaccination clinic, what better way to unwind than updating those last two hosts in the #homelab?
