When running "apk upgrade" on a fresh sxmo 1.3.0 image, the following error is seen when trying to rebuild the initramfs: ``` -snip- (129/131) Upgrading sxmo-xdm-config-openrc (0.2.1-r1 -> 0.2.2-r0) (130/131) Upgrading postmarketos-ui-sxmo (1.3.0-r1 -> 1.3.2-r0) Executing postmarketos-ui-sxmo-1.3.2-r0.post-upgrade * rc-update: sxmo-pinephone already installed in runlevel `default'; skipping * rc-update: modemmanager already installed in runlevel `default'; skipping * rc-update: xdm already installed in runlevel `default'; skipping (131/131) Purging llvm10-libs (10.0.1-r1) Executing busybox-1.33.0-r4.trigger Executing glib-2.66.7-r1.trigger Executing eudev-3.2.10-r0.trigger Executing dbus-1.12.20-r2.trigger Executing ca-certificates-20191127-r5.trigger Executing kmod-28-r0.trigger depmod: WARNING: could not open modules.order at /lib/modules/5.10.12: No such file or directory depmod: WARNING: could not open modules.builtin at /lib/modules/5.10.12: No such file or directory Executing fontconfig-2.13.1-r3.trigger Executing mkfontscale-1.2.1-r1.trigger Executing postmarketos-mkinitfs-0.22-r0.trigger ==> initramfs: creating /boot/initramfs-postmarketos-allwinner Scanning kernel module dependencies...

Possible solutions: * Default boot_size be increased to at least 160M, with 200M preferable. * Create new initramfs files outside boot partition, then overwrite. * Trust users of pmbootstrap to predict and use safe value for boot_size option. * Have script remove existing initramfs from /boot before building new one **Additional information:** Comparison of libLLVM-##.so files sizes (output from `du`, in bytes): ``` 62292864 old/usr/lib/libLLVM-10.so 88811280 new/usr/lib/libLLVM-11.so ``` `df -h /boot` output prior to upgrade: ``` Filesystem Size Used Avail Use% Mounted on /dev/mmcblk0p1 114M 75M 33M 81% /boot ``` `df -h /boot` output after (manual) upgrade: ``` Filesystem Size Used Avail Use% Mounted on /dev/mmcblk0p1 114M 87M 21M 81% /boot ```
