10 bool "Enable systemd support"
11 default n
12 help
13 If you plan to use busybox daemons on a system where daemons
14 are controlled by systemd, enable this option.
15 If you don't use systemd, it is still safe to enable it,
16 but the downside is increased code size.
17 config BUSYBOX_CONFIG_FEATURE_RTMINMAX
18 bool "Support RTMIN[+n] and RTMAX[-n] signal names"
19 default n
20 help
21 Support RTMIN[+n] and RTMAX[-n] signal names
22 in kill, killall etc. This costs ~250 bytes.

47 default y
48 help
49 This option makes top (and ps) ~20% faster (or 20% less CPU hungry),
50 but code size is slightly bigger.
51
52 config BUSYBOX_CONFIG_FEATURE_ETC_NETWORKS
53 bool "Support for /etc/networks"
54 default n
55 help
56 Enable support for network names in /etc/networks. This is
57 a rarely used feature which allows you to use names
58 instead of IP/mask pairs in route command.

61 bool "Use termios to manipulate the screen"
62 default n
63 depends on BUSYBOX_CONFIG_MORE || BUSYBOX_CONFIG_TOP || BUSYBOX_CONFIG_POWERTOP
64 help
65 This option allows utilities such as 'more' and 'top' to determine
66 the size of the screen. If you leave this disabled, your utilities
67 that display things on the screen will be especially primitive and
68 will be unable to determine the current screen size, and will be
69 unable to move the cursor.

83 Line editing code uses on-stack buffers for storage.
84 You may want to decrease this parameter if your target machine
85 benefits from smaller stack usage.

144 depends on BUSYBOX_CONFIG_FEATURE_EDITING
145 help
146 Allow usage of "ESC [ 6 n" sequence. Terminal answers back with
147 current cursor position. This information is used to make line
148 editing more robust in some cases.
149 If you are not sure whether your terminals respond to this code
150 correctly, or want to save on code size (about 400 bytes),
151 then do not turn this option on.
152
153 config BUSYBOX_CONFIG_FEATURE_NON_POSIX_CP
154 bool "Non-POSIX, but safer, copying to special nodes"
155 default y
156 help
157 With this option, "cp file symlink" will delete symlink
158 and create a regular file. This does not conform to POSIX,
159 but prevents a symlink attack.
160 Similarly, "cp file device" will not send file's data
161 to the device. (To do that, use "cat file >device")
162
163 config BUSYBOX_CONFIG_FEATURE_VERBOSE_CP_MESSAGE

170 $ cp file /vmlinuz/file

172 If this feature is not enabled, they will be, respectively:
173 cp: cannot create '/does_not_exist/file': No such file or directory
174 cp: cannot stat '/vmlinuz/file': Not a directory
175 This will cost you ~60 bytes.

185 stack buffer if mmap fails.

187 config BUSYBOX_CONFIG_FEATURE_SKIP_ROOTFS
188 bool "Skip rootfs in mount table"
189 default n
190 help
191 Ignore rootfs entry in mount table.
192
193 In Linux, kernel has a special filesystem, rootfs, which is initially
194 mounted on /. It contains initramfs data, if kernel is configured
195 to have one. Usually, another file system is mounted over / early
196 in boot process, and therefore most tools which manipulate
197 mount table, such as df, will skip rootfs entry.
198
199 However, some systems do not mount anything on /.
200 If you need to configure busybox for one of these systems,
201 you may find useful to turn this option off to make df show
202 initramfs statistic.
203
204 Otherwise, choose Y.

211 Use clock_gettime(CLOCK_MONOTONIC) syscall for measuring
212 time intervals (time, ping, traceroute etc need this).
213 Probably requires Linux 2.6+. If not selected, gettimeofday
214 will be used instead (which gives wrong results if date/time
215 is reset).

221 Use ioctl names rather than hex values in error messages
222 (e.g. VT_DISALLOCATE rather than 0x5608). If disabled this
223 saves about 1400 bytes.
