我知道，有很多主题，但是我还不清楚。

首先，我有 systemd 服务、脚本和 udev 规则，它们在 USB 设备连接时运行。这按预期工作。

[Unit]
After=run-media-serg-GARMIN.mount
Description=Backup garmin activities when Garmin 830 is connected
Requires=run-media-serg-GARMIN.mount

[Service]
Environment="LOCALE_ARCHIVE=/nix/store/ckkhm153z75sw6z5nr277kvn2pi4z8jy-glibc-locales-2.35-224/lib/locale/locale-archive"
Environment="PATH=/nix/store/l6jgwxkc3jhr029vfzfwzcy28iyckwsj-coreutils-9.1/bin:/nix/store/gn1s1s5z19cf0wiir2cd38jckcjc6kn6-findutils-4.9.0/bin:/nix/store/pvb117r7fhwb08717ks21a6y9hlnp63b-gnugrep-3.7/bin:/nix/store/v0hg83sdv4v51c0prmdigry6wdmmpzmp-gnused-4.8/bin:/nix/store/jnrdsg66spsm9n9amz5lspigdds7nrmf-systemd-251.16/bin:/nix/store/l6jgwxkc3jhr029vfzfwzcy28iyckwsj-coreutils-9.1/sbin:/nix/store/gn1s1s5z19cf0wiir2cd38jckcjc6kn6-findutils-4.9.0/sbin:/nix/store/pvb117r7fhwb08717ks21a6y9hlnp63b-gnugrep-3.7/sbin:/nix/store/v0hg83sdv4v51c0prmdigry6wdmmpzmp-gnused-4.8/sbin:/nix/store/jnrdsg66spsm9n9amz5lspigdds7nrmf-systemd-251.16/sbin"

ExecStart=/nix/store/fqr3f89hajwb0s5s50kd72jp8a93xipm-garmin-backup/bin/garmin-backup
Type=forking

ACTION=="change", SUBSYSTEM=="block",
        ENV{ID_VENDOR_ID}=="091e", ENV{ID_MODEL_ID}=="2c32", ENV{ID_SERIAL}=="Garmin_GARMIN_Flash-0:0",
    ENV{SYSTEMD_WANTS}=="${garminService}.service"

但我不太喜欢的是，挂载点是硬编码的，例如 systemd 服务中的“after”和“requires”行取决于我当前的用户名。而且我不能确定挂载点在另一个桌面环境中总是完全相同。

我解决这个问题的想法之一是：

  1. 在 udev 规则中禁用自动挂载
  2. 创建 systemd 挂载服务，它将始终挂载在同一位置。

但也许有一个更简单的解决方案。你能帮我吗？
