Subject: [PATCH RESEND 1/3] init/main.c: log arguments and environment passed to init
Date: Sat, 23 Nov 2019 16:40:37 -0500	[thread overview]
Message-ID: <20191123214039.139275-2-nivedita@alum.mit.edu> (raw)
In-Reply-To: <20191123214039.139275-1-nivedita@alum.mit.edu>

Extend logging in `run_init_process` to also show the arguments and
environment that we are passing to init.
