每次重新启动后都有一个新的挂载点

我有一个带有 Arch Linux 和 Kodi 的 Raspberry Pi。我尝试通过Systemd的新方式进行所有配置，即通过创建Systemd单元。例如，不要在启动时使用以下命令配置挂载点/etc/fstab文件，我是按单位做的.mount。

我使用 Udisks2 和 Polkit 进行了自动挂载配置。

当我不拔下硬盘并命令系统重新启动时，我看到硬盘已安装在以下新目录中/媒体每次启动后。例如，假设在重新启动之前，HDD 已安装在/媒体/无标题。重新启动后，它将（自动）安装在/媒体/无题1。下次下一次/媒体/无题2等等。我希望它始终安装在/媒体/无标题。

也许，解决方案是这里，但我不知道。

编辑：我有以下安装单位（在/etc/systemd/系统目录）：

引导安装单元（启动挂载）：

# boot.mount
[Unit]
Description=Boot partition

[Mount]
What=/dev/disk/by-uuid/<BOOT_PART_UUID>
Where=/boot
Type=vfat
Options=defaults

[Install]
WantedBy=multi-user.target

根 （/) 安装单元 (-。山）：

# -.mount
[Unit]
Description=Root partition

[Mount]
What=/dev/disk/by-uuid/<ROOT_PART_UUID>
Where=/
Type=ext4
Options=noauto,x-systemd.automount

[Install]
WantedBy=multi-user.target

家用安装装置（主页挂载）：

# home.mount
[Unit]
Description=Home partition

[Mount]
What=/dev/disk/by-uuid/<HOME_PART_UUID>
Where=/home
Type=ext4
Options=noauto,x-systemd.automount

[Install]
WantedBy=multi-user.target

Polkit 规则是（根据/etc/polkit-1/rules.d目录）：

50-udisks.规则

// 50-udisks.rules
polkit.addRule(function(action, subject) {
    var YES = polkit.Result.YES;
    var permission = {
        //// only required for udisks1:
        //"org.freedesktop.udisks.filesystem-mount": YES,
        //"org.freedesktop.udisks.filesystem-mount-system-internal": YES,
        //"org.freedesktop.udisks.luks-unlock": YES,
        //"org.freedesktop.udisks.drive-eject": YES,
        //"org.freedesktop.udisks.drive-detach": YES,
        // only required for udisks2:
        "org.freedesktop.udisks2.filesystem-mount": YES,
        "org.freedesktop.udisks2.filesystem-mount-system": YES,
        "org.freedesktop.udisks2.encrypted-unlock": YES,
        "org.freedesktop.udisks2.eject-media": YES,
        "org.freedesktop.udisks2.power-off-drive": YES,
        // required for udisks2 if using udiskie from another seat (e.g. systemd):
        "org.freedesktop.udisks2.filesystem-mount-other-seat": YES,
        "org.freedesktop.udisks2.encrypted-unlock-other-seat": YES,
        "org.freedesktop.udisks2.eject-media-other-seat": YES,
        "org.freedesktop.udisks2.power-off-drive-other-seat": YES
    };
    if (subject.isInGroup("storage")) {
        return permission[action.id];
    }
});

（我使用的是 Udisks2。）

48-shutdown-power-group.rules 关闭电源组规则

// 48-shutdown-power-group.rules
polkit.addRule(function(action, subject) {
    if ((action.id == "org.freedesktop.login1.reboot" ||
        action.id == "org.freedesktop.login1.reboot-multiple-sessions" ||
        action.id == "org.freedesktop.login1.power-off" ||
        action.id == "org.freedesktop.login1.power-off-multiple-sessions" ||
        action.id == "org.freedesktop.login1.suspend" ||
        action.id == "org.freedesktop.login1.suspend-multiple-sessions" ||
        action.id == "org.freedesktop.login1.hibernate" ||
        action.id == "org.freedesktop.login1.hibernate-multiple-sessions") && subject.isInGroup("power"))
    {
        return polkit.Result.YES;
    }
});

udev 规则（下/etc/udev/rules.d目录）：

99-udiks2.规则

# 99-udisks2.rules
# UDISKS_FILESYSTEM_SHARED
# ==1: mount filesystem to a shared directory (/media/VolumeName)
# ==0: mount filesystem to a private directory (/run/media/$USER/VolumeName)
# See udisks(8)
ENV{ID_FS_USAGE}=="filesystem|other|crypto", ENV{UDISKS_FILESYSTEM_SHARED}="1"
