How to create a container with Gentoo based on systemd?

I tried to use -t download, there is only funtoo available, no gentoo. Old script “/usr/share/lxc/templates/lxc-gentoo” supposed to use SysV-init based containers, don’t work with systemd-based containers.
How to make gentoo available in that “download” list? Host system is Debian 11, if that important.

I can confirm its not in the list.

The only difference between funtoo and gentoo in the images list website is that gentoo doesn’t have a “default” variant. https://uk.lxd.images.canonical.com/

@amikhalitsyn can you take a look and see if lxc-create supports non-default variants.
@monstermunchkin is there a reason gentoo image doesn’t have a default variant?

I’ve managed to get “openrc” variants of gentoo using this:
lxc-create -t download -n my_container -- --variant="openrc"

We are filtering out other variants except the “default” here:

github.com

lxc/lxc/blob/master/templates/lxc-download.in#L250

      
        
            
            
# Parse it
            echo ""
            echo "---"
            printf "DIST\tRELEASE\tARCH\tVARIANT\tBUILD\n"
            echo "---"
            while IFS=';' read -r f1 f2 f3 f4 f5 f6; do
              [ -n "${DOWNLOAD_DIST}" ] && [ "$f1" != "${DOWNLOAD_DIST}" ] && continue
              [ -n "${DOWNLOAD_RELEASE}" ] && [ "$f2" != "${DOWNLOAD_RELEASE}" ] && continue
              [ -n "${DOWNLOAD_ARCH}" ] && [ "$f3" != "${DOWNLOAD_ARCH}" ] && continue
              [ -n "${DOWNLOAD_VARIANT}" ] && [ "$f4" != "${DOWNLOAD_VARIANT}" ] && continue
              [ -z "${f5}" ] || [ -z "${f6}" ] && continue
            
            
  printf "%s\t%s\t%s\t%s\t%s\n" "${f1}" "${f2}" "${f3}" "${f4}" "${f5}"
              unset f1 f2 f3 f4 f5 f6
            done < "${DOWNLOAD_TEMP}/index"
            echo "---"
            
            
if [ "${DOWNLOAD_LIST_IMAGES}" = "true" ]; then
              exit 1
            fi

I’m not sure that we need to filter out variants on the listing stage.

`lxc-create -t download -n my_container -- --variant="systemd"`

also works.
