Yeah, disk space is pretty cheap these days.  I "grew up" in computing when that was not the case, however--and I guess it's still a little hard for me to look at a disk that has 6% utilization.

OPNsense is running on a slice of a bigger disk that's also used for other things, so I could have used some of the space for something else.  Or I can just add another disk.  Strange that we live in a world of $20 SSDs and video cards & CPUs you can't even buy at $1000.

That makes sense about the dependencies.  I didn't think about that.  Usually it's bloat that gets added in updates, not dependencies removed.  Good that the developers are keeping up on housekeeping like that.

Don't have the answer either but... I have the exact same issue and the Internet took me here.  I suspect I've misconfigured something horribly but I'm not sure what.

Okay--now this is a weird one, and I couldn't find anything about it online.  It's more of a curiosity than an issue, but I would like to understand what's going on.

I created a new OPNsense firewall, using a freshly-downloaded OPNsense-21.1-OpenSSL-dvd-amd64.iso image.  Following the guidelines here: https://docs.opnsense.org/manual/hardware.html I gave it a 40 GB root disk for a "reasonable" install.

I was a little surprised that it only ended up taking 2.1 GB after install.  I'm not quite sure why the hardware guide recommends so much storage.  In fact, the "recommended" size is 120GB, which would've been <2% used.

But that's not my main question.  After installing, I immediately updated from the System->Firmware->Updates page, and that brought me to 21.1.5.  To my surprise, disk usage dropped by a full 300 MB, down to 1.8 GB.  I can't remember seeing a software update take up less space than it's predecessor--and certainly never by a full 15%.

I did install a whole slew of plugins, and that brought me back to 1.9 GB used.  With everything configured and running fine for a while now, it doesn't seem to be growing much.  But I'm wondering, did the fresh DVD install just come with 300 MB of cruft that the update cleared out?  I have no idea what files went into the chipper as I didn't do a before/after comparison.

I'm also running OPNsense under esxi, and have no issues.  I have multiple other VMs on that same host, and they all have connectivity to OPNsense, each other, my desktop/laptops, and the Internet.

What does your vswitch setup look like?  I have my management / VM traffic and external traffic segregated onto separate vswitches.  OPNsense is connected to both switches and routes between them, and everything seems fine.

Hmm, that link doesn't seem to work for me.  Is it still correct?
