 2:36.83 * ~78%  3287) obj-firefox-tup/toolkit/library/rust: RUSTC serde_json v1.0.26 Host -> [libserde_json-0a4afa080162e235.rlib]

 2:36.83 tup error: Missing input dependency - a file was read from, and was not specified as an input link for the command. This is an issue because the file was created from another command, and without the input link the commands may execute out of order. You should add this file as an input, since it is possible this could randomly break in the future.

FWIW, I have the following in my mozconfig.

ac_add_options --with-ccache
ac_add_options --enable-application=browser
ac_add_options --enable-debug
ac_add_options --disable-optimize
export TUP="$HOME/.mozbuild/tup/tup"
ac_add_options --enable-build-backends=Tup
