当我编译Linux内核生成bzImage
、rootfs
使用创建busybox
、重启电脑执行时dmesg
,发现报警。tomoyo-init
我的定制系统中没有该可执行文件/sbin
,但我的另一台计算机已debian12
安装,并且是相同的。请问这是怎么回事?
有关以下的一些信息dmesg

我看到网上有人说和这个有关grub.cfg
。我的定制系统grub.cfg
如下:
root@dobot:~# cat /boot/grub/grub.cfg
# Begin cfg
set default=0
set timeout=3
menuentry "GNU/Linux, Dobot-6.4.0-rt8" {
linux (hd0,gpt2)/bzImage rw root=/dev/mmcblk0p3 net.ifname-policy=onboard,path,slot
initrd (hd0,gpt2)/initrd.img-6.4.0-rt8
}
答案1
这不是一个“警报”,它只是一条消息,表明TOMOYO Linux MAC 子系统未激活,因为用户空间激活已配置但/sbin/tomoyo-init
不可用。
看相关内核配置有关详细信息:看来您启用了SECURITY_TOMOYO
,没有SECURITY_TOMOYO_OMIT_USERSPACE_LOADER
,并且没有提供所需的用户空间工具。
如果您不打算使用 TOMOYO Linux,您应该SECURITY_TOMOYO
在构建配置中禁用它。如果您要使用它,您应该提供适当的工具(tomoyo-tools
Debian 中的软件包)和配置。
