There was a problem hiding this comment. Minimal image doesn't have unnatended-upgrade service - probably don't need to bother with this? |

There was a problem hiding this comment. 🧩 Analysis chain🌐 Web query:
💡 Result: zswap.enabled is not a valid Linux sysctl key under /proc/sys/vm/. It is configurable via kernel command line (e.g., zswap.enabled=1) or module parameter (echo 1 > /sys/module/zswap/parameters/enabled). Writing vm.compact_memory=1 via sysctl triggers memory compaction across all zones (if CONFIG_COMPACTION is enabled), moving free memory into contiguous blocks to reduce fragmentation. This aids allocations like huge pages, though processes compact as needed. Citations:

There was a problem hiding this comment. Append the badge overlay instead of replacing This assignment discards any overlays already supplied by the user, so BeagleBadge owners can't combine the mandatory E-Ink overlay with their own add-ons. 🩹 Proposed fix-check_beaglebadge=if test "${fdtfile}" = "ti/k3-am62l3-badge.dtb"; then rdaddr=0x84900000; name_overlays=ti/k3-am62l3-badge-eink-gdey042t81.dtbo; fi

Fix the hardware description on Line 1.
This looks copied from another TI board and advertises
2xGBE OSPI HDMI, which does not match the badge-specific E-Ink/CC33xx setup introduced below. This string is shown during interactive board selection, so it needs to describe the actual hardware.Based on learnings: in Armbian board configuration files, the first-line comment must be a proper hardware feature description because it is used during interactive compilation.
