Bug#916122: pbuilder: misleading warning about missing cgroups

[Thorsten Glaser]

Package: pbuilder
Version: 0.231.1

Same here, I got a new fat yellow warning about cgroups not being
available which REALLY stands out…

… after I went through considerable pain to make cgroups available
so podman+crun can work.

My suggestion for this is:

1. in /usr/share/pbuilder/pbuilderrc change
-USECGROUP=yes
+USECGROUP=default

2. in /usr/lib/pbuilder/pbuilder-checkparams, before line…

    391     if [ "$USECGROUP" = "yes" ]; then

… add this:

        if [ "$USECGROUP" = "default" ]; then
                if test -d /run/systemd/system && \
                    command -v systemctl >/dev/null 2>&1; then
                        USECGROUP=yes
                else
                        # cgroups currently are only supported in
                        # pbuilder for systemd so quietly disable
                        USECGROUP=no
                fi
        fi

… and further below, change…

        else
            log.w "cgroups are not available on the host, not using them."
            USECGROUP=not-available
        fi

… to this (for when someone does not set =default):

        elif test -d /run/systemd/system && \
            command -v systemctl >/dev/null 2>&1; then
                log.w "cgroups are not available on the host, not using them."
                USECGROUP=not-available
        else
                log.i "cgroups currently only supported with systemd, 
disabling."
                USECGROUP=not-available
        fi

(note, untested)
