r/coreos

• Having a already running CoreOS server

• Trying to fulfill the following guide to get homeassistant-matter-hub working:

• Already created files like /etc/sysctl.d/50-ipv6.conf or /etc/sysctl.d/100-sysctl.config or direclty editing /etc/sysctl.conf did not help to change the following values

net.ipv6.conf.all.forwarding=0
net.ipv6.conf.all.accept_ra=1
net.ipv6.conf.all.accept_ra_rt_info_max_plen=64

or

net.ipv6.conf.all.forwarding=0
net.ipv6.conf.enp5s0.accept_ra=1
net.ipv6.conf.enp5s0.accept_ra_rt_info_max_plen=64

Can someone give me a hint?

After creating/editing the files above i still get something like

$ sudo sysctl -n net.ipv6.conf.all.forwarding
1

Hey, I am trying to use coreos to use coreos and because my server has very little ram I wanted to add a swap partition to my os. My ignition file looks like this and it also boots and installes evering i define but it uses the default partition layout and overrides my layout. I only found sources on how to enable swap with a partition file, but that it not recommended for xfs & btrfs filesystems so I would still need to modify the default partition layout. Has someone a idea on how I could create a swap partition throught the ignition file?

I'm running k3s on a cluster of six coreos VMs. The version of coreos running on them is "Fedora CoreOS 39.20240309.3.0". uname -a returns...

Linux k0 6.7.7-200.fc39.x86\_64 #1 SMP PREEMPT\_DYNAMIC Fri Mar  1 16:53:59 UTC 2024 x86\_64 GNU/Linux

Is it possible to hold the kernel version back at something much earlier? The reason i'm asking is that the mssql container image is having trouble with version 6.7. Until that bug gets resolved i'd like to get my mssql container running in my cluster again.
