# This file enables baseline features, such as io_uring,

# userspace merge, etc. But sets compression method to none.

# This .mk file also removes snapuserd from vendor ramdisk,

# as T launching devices will have init_boot which has snapuserd

# in generic ramdisk.

# T launching devices should include this .mk file, and configure

# compression algorithm by setting

# PRODUCT_VIRTUAL_AB_COMPRESSION_METHOD to gz or brotli. Complete

# set of supported algorithms can be found in

# system/core/fs_mgr/libsnapshot/cow_writer.cpp
