linux - 添加用户以在 Buildroot 中为自定义包创建

Question

我正在 buildroot 中添加一个包。特别是 fcron-3.2.1。文档说将其放入包 makefile (fcron.mk) 中:

LIBFOO_USERS

Lists the users to create for this package, if it 
installs a program you want to run as a specific user (e.g. as a 
daemon, or as a cron-job). The syntax is similar in spirit to the 
makedevs one, and is described in the Chapter 24, Makeusers syntax 
documentation. This variable is optional.

所以我的 fcron.mk 文件看起来像这样:

#############################################################
#
# fcron
#
#############################################################

FCRON_VERSION = 3.2.1
FCRON_OVERRIDE_SRCDIR = ../fcron-3.2.1
FCRON_OVERRIDE_RSYNC = YES
FCRON_INSTALL_STAGING = YES
FCRON_INSTALL_TARGET = YES
FCRON_SITE_METHOD = local
FCRON_CONF_OPTS = --enable-shared
FCRON_SITE = www.nomad-digital.com

define FCRON_USERS
    fcron -1 fcron -1 * - - - Fcron daemon
endef

$(eval $(autotools-package))

当我尝试在 buildroot 中安装时，出现以下错误。

>>> fcron custom Installing to staging directory
Checking if group fcron exists ... no.
Would you like to add fcron in /etc/passwd with the following command ?
    groupadd fcron
If you use NYS, ldap, etc, you should add the group manually (say no here)
Please answer with 'y' or 'n' (default: 'y'): y
groupadd: Permission denied
groupadd cannot lock /etc/group; try again later.
Group "fcron" does not exists : please create it or choose another groupname with configure script.

我有一种感觉，我试图在主机上创建一个用户，而不是在我的 buildroot 镜像中，但即使我在上面回答“n”，它仍然没有通过，只是说请创建一个用户.我是否在 buildroot 中正确创建了所需的用户和组？

Answer 1

是 fcron 构建系统尝试将用户和组添加到主机，因为它显然不考虑在暂存目录中安装。您需要告诉 fcron 构建系统不要在安装期间添加用户和组。如果这在 fcron 配置选项中不是很明显，您可以看看发行版是如何解决它的，它们也会有同样的问题。可能您需要修补其 Makefile.am 并在 fcron.mk 中设置 FCRON_AUTORECONF = YES。
