Currently alpine script does not use https to fetch the image

https://github.com/vpsfreecz/build-vpsfree-templates/blob/master/include/alpine.sh#L5

I'm willing to try to give a shot debugging this, but README.md is bit short on details how to run this. Could I get some pointers? Do we have a wiki page somewhere for that or something?

Remote console should be enabled in all templates by default, see http://kb.vpsfree.cz/konfigurace_a_zabezpeceni/vzdalena_konzole

sshd sometimes does not start on boot on Fedora 30, even though it is enabled. It happens while testing built images and on staging as well. No idea what's going on, there's not even any attempt at starting it, the service is sometimes just ignored.

I installed fresh copy of template CentOS 9 Stream and when tried install any package I got error related to public key. In dnf.log I noticed: dnf.exceptions.Error: GPG check FAILED

dbus is not installed by default, but when installed, the VPS will not boot at all. It fails on:

Process: 237 ExecStart=/usr/bin/dbus-daemon --system --address=systemd: --nofork --nopidfile --systemd-activation (code=exited, status=206/OOM_ADJUST)

So we should add an override to the template and disable OOMScoreAdjust on dbus.service.

UTC timezone is broken in Debian 11 image.

Use clean CentOS 9 Stream installation.
run command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm

to install the latest epel, unfortunately installation fails with message
"Key import failed (code 2). Failing package is: epel-next-release-9-2.el9.noarch"

freshclam processes from multiple VPS tend to go crazy all at once, overloading the nodes. We can't really help it if people install it, but we could add override to all templates using systemd and limit the CPU usage, e.g.:

mkdir -p /etc/systemd/system/clamav-freshclam.service.d
cat <<EOF > /etc/systemd/system/clamav-freshclam.service.d/override.conf
[Service]
CPUQuota=25%
CPUWeight=10
EOF

I fix with this cmd

update-locale LC_ALL=en_US.UTF-8
update-locale LANGUAGE=en_US.UTF-8
update-locale LANG=en_US.UTF-8

From the 01/Feb/2020, RHEL will be for free for 16 devices for "small production workloads". Link

So it would be nice to have RHEL 8 template for using.
