For devices that use UEFI boot, ie where /boot is a vfat partition,
this commit
introduced a regression that causes the partition to not be mounted in some cases,
which then causes boot to fail with an "initramfs-extra not found" error.
Specifically, the list of devices affected are those which use the following kernels:
linux-postmarketos-gratelinux-postmarketos-qcom-msm8916linux-ayn-odinlinux-postmarketos-qcom-sc8180x
A fix is being worked on. Meanwhile, users of these devices are recommended to not install updates.
If you have already installed the update and have a device that fails to boot
with the "initramfs-extra not found" error, you can recover the installation by booting
a working image, chroot'ing into the original installation,
editing /usr/share/initramfs/init_functions.sh in this way:
-mount_opts="-t vfat $mount_opts,umask=0077,nosymfollow,codepage=437,iocharset=ascii"
+mount_opts="-t vfat $mount_opts,umask=0077,nosymfollow,codepage=437"
... and rebuilding the initramfs with mkinitfs
