i also tried using the "source-branch: raspi2" argument in the snapcraft.yaml instead of using teh master branch and the "source-tag:" option, but this results in the same big size ...
additionally i'd like to remark that due to the transactional nature of UbuntuCore we need to keep the kernel three times on the device for the automatic rollback feature ... the current size would mean 2.1GB for compressed kernels alone. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1851233 Title: building a snap from the eoan tree using the raspi2 defconfig results in gigantic snap package Status in linux package in Ubuntu: Confirmed Bug description: typically a kernel snap built from the kernel.ubuntu.com tree using the raspi2 defconfig results in a snap package that is below 150MB in size: $ ls -lh pi2-kernel_raspi2-4.4.0-1110.snap -rw------- 1 root root 129M Jun 4 15:01 pi2-kernel_raspi2-4.4.0-1110.snap trying to build a similar snap from the source tree for eoan seems to add several 100MB of unused modules to the binary, resulting in a 700MB+ snap package $ ls -lh pi4-kernel_raspi2-5.3.0-1008.9_armhf.snap -rw-r--r-- 1 ogra ogra 712M Oct 24 15:46 pi4-kernel_raspi2-5.3.0-1008.9_armhf.snap the snapcraft.yaml used for both cases is https://paste.ubuntu.com/p/J563CDsdGW/ with modified source tree and name (one pointing to xenial. the other to eoan) but no other changes between the two above packages. seems in eoan the defconfig enables a ton of additional modules (1.6G uncompressed) that have not been there before: $ sudo mount -o loop pi4-kernel_raspi2-5.3.0-1008.9_armhf.snap /mnt $ du -hcs /mnt/* 3.1M /mnt/System.map-5.3.1+ 211K /mnt/config-5.3.1+ 906K /mnt/dtbs 475M /mnt/firmware 4.5M /mnt/initrd-5.3.1+.img 7.0M /mnt/kernel.img 512 /mnt/meta 1.6G /mnt/modules 2.1G total $ that will result in unreasonable big ubuntu core images, the list of included modules should be trimmed for this flavour To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1851233/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
