The poky repository master branch is no longer being updated.
You can either: a) switch to individual clones of bitbake, openembedded-core, meta-yocto and yocto-docs b) use the new bitbake-setup You can find information about either approach in our documentation: https://docs.yoctoproject.org/ Note that "poky" the distro setting is still available in meta-yocto as before and we continue to use and maintain that. Long live Poky! Some further information on the background of this change can be found in: https://lists.openembedded.org/g/openembedded-architecture/message/2179 Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

7# Simple initramfs module intended to mount a read-write (RW)
8# overlayfs on top of /, keeping the original root filesystem
9# as read-only (RO), free from modifications by the user.
10#
11# NOTE: The read-only IMAGE_FEATURE is not required for this to work
12#
13# This script is based on the overlay-etc.bbclass, which sets up
14# an overlay on top of the /etc directory, but in this case allows
15# accessing the original, unmodified rootfs at /rofs after boot.
16#
17# It relies on the initramfs-module-rootfs to mount the original
18# root filesystem, and requires 'overlayrootrwdev=<foo>' to be passed as a
19# kernel parameter, specifying the device/partition intended to
20# use as RW.
21# Mount options of the RW device can be tweaked with 'overlayrootfstype='
22# (defaults to 'ext4') and 'overlayrootfsflags=' ('defaults').
23#
24# This module needs to be executed after the initramfs-module-rootfs
25# since it relies on it to mount the filesystem at initramfs startup
26# but before the finish module which normally switches root.
27# After overlayroot is executed the usual boot flow continues from
28# the real init process.
29#
30# If something goes wrong while running this module, the rootfs
31# is still mounted RO (with no overlay) and the finish module is
32# executed to continue booting normally.
33#
34# It also has a dependency on overlayfs being enabled in the
35# running kernel via KERNEL_FEATURES (kmeta) or any other means.
