From 9529115c4ce87d4faecd1c55e547162efe74d629 Mon Sep 17 00:00:00 2001 From: Kang-Che Sung Date: Wed, 4 Jan 2017 12:29:04 +0100 Subject: [PATCH] shell: clarify help text of CONFIG_{SH,BASH}_IS_* options Mention the behavior if user selects CONFIG_SH_IS_ASH but not CONFIG_ASH. We will be explicit that invocations like "busybox ash" will not work for such configuration. Also clarify help text of CONFIG_BASH_IS_* that bash compatibility in ash is not complete. (It shouldn't be anyway - ash can't support every bash quirk out there.)
