okay bestie, pull up a chair — this is mount.zfs(8) from the System Manager's Manual, and honestly? it's a tiny little page but it's doing SO much behind the scenes. she's the backstage crew of your filesystem, fr fr. 💅

✨ NAME ✨

mount.zfs — mount ZFS filesystem 💖

🦋 SYNOPSIS 🦋

mount.zfs [-sfnvh] [-o options] dataset mountpoint

that's it. that's the whole vibe check. dataset and mountpoint, plus some flags you probably won't touch. 👑

🌸 DESCRIPTION 🌸

okay so. the mount.zfs helper is the little go-between that mount(8) uses when it needs to mount filesystem snapshots and mountpoint=legacy ZFS filesystems. she also gets called by zfs(8) whenever the ZFS_MOUNT_HELPER environment variable is not set. multitasking queen. 🫶

but listen — the actual guidance here is that you, the user, should invoke either mount(8) or zfs(8) in most cases. mount.zfs is the helper doing the behind-the-scenes work, not the main character you call directly. (respectfully, let the frontends handle it. that's the assignment. 💀)

the options are handled according to the Temporary Mount Point Properties section over in zfsprops(7) — with the exception of the ones described below, which get their own lil rules. 🎀

and one more thing: if /etc/mtab is a regular file and -n was not specified, it will be updated via libmount. yes bestie, she keeps receipts. 📝

💖 OPTIONS 💖

  • -s — ignore unknown (sloppy) mount options. like when someone brings a plus-one you didn't invite and you're just like... sure, whatever, come in. 🙈
  • -f — do everything except actually executing the system call. all dressed up, no place to go. iconic fake-out. ✨
  • -n — never update /etc/mtab. she will NOT be taking notes. 💅
  • -v — print the resolved mount options and parser state. show us the lore, bestie. 🔍
  • -h — print the usage message. the "help me help you" button. 💜
  • -o zfsutil — this private flag is how you tell mount.zfs that mount(8) is being called by the zfs(8) command. it's the secret handshake. iykyk. 🤝
