+Revisit these options:
+	CONFIG_FEATURE_INSTALLER
+		would users really need this?
+		space difference looks negligible
+	CONFIG_LOCALE_SUPPORT
+		space difference looks negligible in code
+		time difference probably negligible:
+			most changes add setlocale() or change strcmp() to strcoll()
+	CONFIG_UNICODE_*
+	CONFIG_FEATURE_SUID_CONFIG
+		might be useful for tuning security settings (like sudo)
+	CONFIG_FEATURE_SYSTEMD
+	CONFIG_FEATURE_ETC_NETWORKS
+	CONFIG_FEATURE_EDITING_VI
+		code added in libbb/lineedit.c looks non-negligible
+		required by POSIX.1 XCU
+	CONFIG_FEATURE_EDITING_SAVEHISTORY
+		Bradley Kuhn would want this enabled ;)
+		code added looks non-negligible
+	CONFIG_FEATURE_TAB_COMPLETION
+		code added is large
+		useful and popular feature
+	CONFIG_BOOTCHARTD
+		might be nice to trace boot time in an OS hackers' build of BusyBox
+	CONFIG_FEATURE_INIT_SCTTY
+	CONFIG_ASH_JOB_CONTROL
+	CONFIG_ASH_BUILTIN_*
+	CONFIG_ASH_CMDCMD
+	CONFIG_ASH_OPTIMIZE_FOR_SIZE
+	CONFIG_CTTYHACK
+		mind this in /etc/inittab
+	CONFIG_FEATURE_MOUNT_NFS
+	CONFIG_FEATURE_MOUNT_CIFS
+	CONFIG_READPROFILE
+		code is a 263-line source file
+		might be nice to do profiling in an OS hackers' build of BusyBox
+	CONFIG_FEATURE_DATE_ISOFMT
+		not in POSIX.1
+		adds no additional code
+		would be nice to have more adoption of ISO 8601
+	CONFIG_ED
+		required by POSIX.1-2008 XCU
+		interactive program, unlikely to ever be used in any shell scripts
+		old and simple editor, unlikely to ever be used by any user
+		vi will be just as easily available to use
+	CONFIG_USE_BB_PWD_GRP
+		will be using EGLIBC's NSS for file/DNS name resolution anyway
+		might as well use it for passwd/group file lookups
+		will use BusyBox's lookup functions with uClibc
+	CONFIG_FEATURE_CHECK_NAMES
+		adds a 62-line source file with one function to the build
+		will end users be adding users and groups to the system?
+General notes:
+	it might be useful to build two BusyBox packages:
+		one configured for end-users
+		one configured for OS hackers
