# APKBUILD based on linux-vanilla aport. Changes:
|
|
# - add findutils makedepend (necessary for the initramfs)
|
|
# - it builds an initramfs - do not use ramdisk.cpio and
|
|
# ramdisk-recovery.cpio, in there, always use the
|
|
# initramfs from the kernel2 partition ("isorec")
|
|
# - directly boot to that initramfs, not only when the recovery
|
|
# key combination was pressed.
|
|
# - use Alpine's busybox-static instead of the pre-compiled
|
|
# binary, that comes with the source
|
|
# - reduce lzo compression because Alpine's busybox doesn't
|
|
# support high compression
|
|
# - add kernel modules installation
|
|
# - add wifi firmware from vendor files
|
|
#
|
|
# Kernel config changes, based on: arch/arm/configs/janice_defconfig
|
|
# - enable devtmpfs (needed for udev -> touch support in weston)
