最近遇到一个有点复杂的问题，研究了半天没解决，想试试用 AI 来搞行不行，之前看有 V 友分享 AI 使用方面的一些经验，感觉现阶段的 AI 应该是能解决我遇到的这个问题的，但我预算有限，想在实际开搞之前先让 V 友帮我预估一下搞定这个问题大概要花多少钱。
问题如下：
dnf --installroot=/var/lib/lxc/f43/rootfs --setopt=reposdir=/etc/yum.repos.d/ --releasever=43 install system-release vi vim systemd passwd dnf rootfiles nmap-ncat openssh-server util-linux iproute iputils perl fzf bash-completion
我在 fedora 44 上用以上这条命令创建了一个 fedora 43 的极简 rootfs ，用 LXC 启动时无法进入控制台，会卡在这里：
root@develop:~# lxc-start -F f43

[root@f43-lxc ~]#
lxc 的配置如下：
root@develop:~# cat /var/lib/lxc/f43/config
lxc.include = /usr/share/lxc/config/common.conf
lxc.rootfs.path = dir:/var/lib/lxc/f43/rootfs
lxc.uts.name = f43-lxc
lxc.mount.auto = sys:rw
如果把 lxc.mount.auto = sys:rw 注释掉就能正常进入控制台，但我需要用这个，同样的配置在 fedora 42 容器里是正常的，但 fedora 43, fedora 44 都有一样的问题。
