我正在尝试使用 systemd 运行挂载脚本。它确实运行了，但挂载点没有出现 ( /with)。如果我/usr/local/sbin/utils-start.bash手动执行，它就可以正常工作。
/etc/systemd/system/test2d.service：
[Unit]
Description=test2d
[Service]
User=root
Type=oneshot
#Start script
ExecStart=/usr/local/sbin/utils-start.bash
RemainAfterExit=yes
[Install]
WantedBy=multi-user.target
/usr/local/sbin/utils-start.bash
/bin/mount -v --make-rshared /
/bin/mount -v --bind /with /with
/bin/mount -v --make-rprivate /with
/bin/mount -v -t tmpfs with-global /with
journalctl -xe结果：

答案1
我找到了问题所在。我不得不跑
systemctl enable test2d
否则它就不起作用。
