To the people who would like to contribute to postmarketOS but haven't, what is stopping you? Or, people who *have* contributed but stopped. (With the exception of just not having time or such)

I'd love to hear some feedback on how our contribution process could be streamlined.

TIL: systemd-modules-load.service, available e.g. on Debian trixie, which allows to load a set of kernel modules during (mid-)early boot, using textfiles in /etc/modules-load.d/.

Combined with:

```
[Unit]
Description=Hardening: disable late loading of kernel modules
Wants=network-pre.target
Before=network-pre.target
After=systemd-modules-load.service
Requires=systemd-modules-load.service

[Install]
WantedBy=multi-user.target

[Service]
Type=oneshot
RemainAfterExit=true
ExecStart=/usr/sbin/sysctl kernel.modules_disabled=1
```

I'm freezing the set of kernel modules loaded on my servers as defense-in-depth.

#Hardening #HardenAllTheThings #Linux

Trying to fix a device asking for proprietary firmware on my #Linux-based system, I `apt -y install firmware-linux-nonfree`. I didn't realize until too late it's a #Debian metapackage for “all the proprietary firmwares (not) fit to download”.

I previously curated a careful selection in /lib/firmware of only ones necessary for my hardware.
I'm left wondering how to clean up further? I generally want to *know* when a proprietary firmware ends up in use. I don't remember which ones are necessary.

A friend asked me about costs etc. in running my own Mastodon (glitch-soc) instance.

My reply might be useful more broadly:

Costs: I run mine on an Intel NUC, for which I paid about ~£200. But I ran for years on a Raspberry Pi, which was fine until my account got a bit big. It consumes some electricity, and I already have an Internet connection with IPv6 and a spare IPv4. So, incrementally, beyond the cost of the hardware, very little.

Time to set up: it took me about 30 minutes *but* I am already familiar with hardening a Linux server, and I build the basic infrastructure automatically. Honestly, this is the bit that would concern me the most, for someone planning on putting a box on the Internet. But it could also be a fun learning exercise.

Time to maintain: a few minutes a month. Upgrades are easy enough. Backups are automatic (because I have automated them).

@cwebber After cringing hard, seeing early #Unix Window Managers like twm and fvwm, it was such a breath of fresh air to see #WindowMaker. I rocked a WindowMaker desktop from about 1998 to about 2002, in #Debian #linux

The first step forward 👀

If a casual chat about #Linux and #FOSS over a curry sounds fun, please come join us! Just reply to me by the end of 21 January so I know numbers for the booking.
