{{ic|fileSystems}} is a NixOS[[Category:NixOS]] option that allows the user to mount filesystems at specific mount points. The mounted filesystems may also be encrypted. Also see [https://nixos.org/manual/nixos/stable/options.html#opt-fileSystems the fileSystem option documentation].

For boot mount options, [https://manpages.ubuntu.com/manpages/noble/en/man8/mount.8.html#filesystem-independent%20mount%20options check here].

Common example filesystem mount. You can put this in configuration.nix:

fileSystems."/mnt/exampleDrive" = {

device = "/dev/disk/by-uuid/4f999afe-6114-4531-ba37-4bf4a00efd9e";

fsType = "exfat";

options = [ # If you don't have this options attribute, it'll default to "defaults"

# boot options for fstab. Search up fstab mount options you can use

"users" # Allows any user to mount and unmount

"nofail" # Prevent system from failing if this drive doesn't mount

];

};

== Making disk visible in your file explorer ==

You might not see the disk in your file explorer (ie GNOME Nautilus). Add to the options: <code>x-gvfs-show</code> and it'll show up.

== Porting /etc/fstab ==

The options specified in /etc/fstab may not be fully compatible with NixOS fileSystems options. For example, here are some options NixOS doesn't recognize that are available on some Linux distributions:

* iocharset

* rw (but it seems to not be needed)

* uid with username rather than actual uid

== Mount order ==

Bind mounting allows a filesystem hierarchy or a file to be mounted at a different mount point. Unlike a symbolic link, a bind mount does not exist on the filesystem itself.~~[3]~~ In the following example, the path {{ic|/olddir}} will be mounted in {{ic|/newdir}}
