  • raspi image-specs root partition size limitation

    From Sebastian Kuzminsky@21:1/5 to All on Wed Feb 22 21:30:01 2023
    Hi there, I'm using image-specs to make a custom Raspberry Pi image for LinuxCNC (https://www.linuxcnc.org). My fork is here: https://github.com/SebKuzminsky/image-specs/

    As you can see I'm mostly adding a bunch of standard debian packages and
    a little bit of system configuration to make things easier for LinuxCNC
    users. Because I'm adding packages, I had to increase the size of the
    root partition.

    I found that if I increase it to 8192M or larger, it fails to resize
    itself to fill the micro-SD card on the first boot. 8000M works fine.
    I'm fine for now staying below 8 gigs, just thought I'd report the issue
    here.

    Thanks for a great tool :-)

    Hmm, I spoke too soon. It's not the larger root partition size that
    breaks the partition resizer, it's installing task-xfce-desktop.

    The debugging continues...

    Ok, false alarm, sort of: the problem was operator error on my part.

    I had added a second "apt: install" step to install some packages in
    addition to the "base system" (outside of the cached root fs tarball).
    That caused the initramfs to be regenerated, but the rpi-resizerootfs
    scripts had already been deleted by then.

    Sorry for the noise, folks.
