我想将/etc/default/grub

我试过使用 augeas 这似乎有这个魔法:
exec { "update_grub":
command => "update-grub",
refreshonly => true,
}
augeas { "grub-serial":
context => "/files/etc/default/grub",
changes => [
"set /files/etc/default/grub/GRUB_CMDLINE_LINUX[last()] cgroup_enable=memory",
],
notify => Exec['update_grub'],
}

它似乎有效,但结果字符串不在引号中,而且我想确保任何其他值都用空格分隔。
GRUB_CMDLINE_LINUX=cgroup_enable=memory

我添加了一个带有测试服务的测试主机:我们称之为“example.com”。
这是测试主机:
/etc/icinga2/conf.d/hosts/example-com:
object Host "example-com" {
//Importiert die generische Host-Vorlage aus der template.conf
import "generic-host"
//IPv4 Adresse
address = "2xx.2xx.2xx.2xx"
//Angabe des Betriebssystemtyps

好的,那么我们有了服务配置:

object Service "http" {
import "generic-service"
host_name = "example-com"
check_command = "http"
