    load the module during installation,
    I don't think this is a good idea. Also modprobe only works until a
    reboot. Also -r is "unload".

    or add a module-load.d conf file
    [1] https://manpages.debian.org/unstable/systemd/modules-load.d.5.en.html
    This can work, and I see a lot of packages in Debian already doing this,
    but is loading the zram module enough for you or do you also need some configuration for it?

    loading the zram module when package installed is enough for me.

    Thanks!

    Hey,

    I'm packaging a package. This package requires the kernel to load the
    zram module to use it.
    How can I implement it?

    The way I can think of is to use "modporbe -r zram" in postinst to
    load the module during installation, or add a module-load.d conf file
    [1] https://manpages.debian.org/unstable/systemd/modules-load.d.5.en.html

    or is there any other recommended way?

    Thanks,
    Clay Stan

    loading the zram module when package installed is enough for me.

    Please use /etc/modules which works everywhere instead of some NIH.

    On the other hand, if you're doing a runtime check, please make sure
    you accept built-in modules, eg by checking -d /sys/module/zswap rather
    than /proc/modules.
