yup, seems this is (surprisingly) on by default ... $ grep DEBUG_INFO parts/kernel/build/.config CONFIG_DEBUG_INFO=y # CONFIG_DEBUG_INFO_REDUCED is not set # CONFIG_DEBUG_INFO_SPLIT is not set CONFIG_DEBUG_INFO_DWARF4=y # CONFIG_DEBUG_INFO_BTF is not set
i'll try a re-build and override that option from snapcraft.yaml ... -- 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
