+You might want to create a second new user so that when you edit jack's login files, you will have a hot spare in case something goes wrong.
Once you have created the user, type `exit` to return to a login prompt and log in as `jack`.
In general, it is a good idea to do as much work as possible as an ordinary user who does not have the power — and risk — of `root`.
If you already created a user and want that user to be able to `su` to `root`, you can add the user to the `wheel` group.
This can be done by editing the file [.filename]#/etc/group#.
-Since this file is sensitive, use the man:pw[8] command to do it for you, for example:
-
-[source,shell]
-....
-# pw groupmod wheel -m jack
-....
-
-To edit configuration files you can use the text editor man:vi[1] or the simpler editor man:ee[1], which is included in the FreeBSD base system footnote:[See extref:{handbook}basics[Text editors, editors] in the FreeBSD Handbook.].
+But first you need to practice man:vi[1], the text editor-or use the simpler text editor, man:ee[1], installed on recent versions of FreeBSD footnote:[See extref:{handbook}basics[Text editors, editors] in the FreeBSD Handbook.].
+Basic editing will be explained later in the crossref:new-users[editing-text,Editing Text] section.
To delete a user, use man:rmuser[8] footnote:[See extref:{handbook}basics[Removing a user, users-rmuser] in the FreeBSD Handbook.].

+ZFS also supports snapshots, which allow you to preserve the state of a filesystem at a particular point in time.
+A snapshot name is appended to the dataset name after the `@` character:
[source,shell]

# zfs snapshot zroot/home@before-edit
....
+Here, `zroot/home` is the dataset name (as shown in `zfs list`), and `before-edit` is an arbitrary snapshot name.

+Snapshots are very useful and have many practical applications.
+For example, boot environments managed with man:bectl[8] use ZFS snapshots to preserve the state of the system before system upgrades, allowing you to boot into the previous state if something goes wrong footnote:[See extref:{handbook}cutting-edge[Upgrading FreeBSD with Boot Environments: bectl,pkgbase-major-zfs] in the FreeBSD Handbook].
