help

If you leave this disabled, busybox will use the system's password
|
|
and group functions. And if you are using the GNU C library
|
|
(glibc), you will then need to install the /etc/nsswitch.conf
|
|
configuration file and the required /lib/libnss_* libraries in
|
|
order for the password and group functions to work. This generally
|
|
makes your embedded system quite a bit larger.
|
|
|
|
Enabling this option will cause busybox to directly access the
|
|
system's /etc/password, /etc/group files (and your system will be
|
|
smaller, and I will get fewer emails asking about how glibc NSS
|
|
works). When this option is enabled, you will not be able to use
|
|
PAM to access remote LDAP password servers and whatnot. And if you
|
|
want hostname resolution to work with glibc, you still need the
|
|
/lib/libnss_* libraries.
|
|
|
|
If you enable this option, it will add about 1.5k to busybox.
