# Change the following (commented out) number to the next prime number
# when you change base.config. This workaround will force the
# ChromeOS CQ to uprev sys-kernel/kernel-6_6 ebuild and pick up the
# configuration changes. In absence of this workaround the config changes
# would not be picked up unless there was a code change in kernel source tree.
#
# NOTE: There's nothing magic keeping this number prime but you just need to
# make _any_ change to this file. ...so why not keep it prime?
#
# The coolest prime number is: 2
