@antifuchs:asf.computerantifuchs so, somewhat serious question though, I don't think boot.kernel.sysfs.class.net.eno8np0.device.sriov_numvfs = 32; is working; the path never triggers, even though the file exists. when I manually start the service, it applies the setting; is that boot.kernel.sysfs handling broken somehow, or am I expecting it to do something impossible? 23:35:29

@sandro:supersandro.deSandro 🐧I had before that I needed to manually load a kernel module early on (as in with the option for it) to make the sysfs paths available when the sysfs service starts13:02:08
@antifuchs:asf.computerantifuchshuh, do you remember what kernel module that is?16:29:16

    initrd.kernelModules = [
      # required for net.netfilter.nf_conntrack_max appearing in sysfs early at boot
      "nf_conntrack"
    ];

@antifuchs:asf.computerantifuchssounds like I need to pull in the one managing the VF functionality, that makes sense20:18:17

@antifuchs:asf.computerantifuchs

systemd-networkd is being a bit weird. networkctl status says /etc/systemd/network/50-vnet.network: RequiredForOnline=yes and ActivationPolicy=manual, this may cause a delay at boot. but the file is:

:;    cat /etc/systemd/network/50-vnet.network
[Match]
Name=vnet*

[Link]
ActivationPolicy=manual
RequiredForOnline=no-carrier
Unmanaged=true

[Network]
ConfigureWithoutCarrier=true

@antifuchs:asf.computerantifuchsRequiredForOnline is not yes?20:18:54
