When setting up roaming profiles in a Windows network which includes Windows 98 desktops, which Samba parameter must be set?

`logon drive` is used to specify a drive letter that should be mapped to the user's home directory upon logon, not for the profile path itself.

The `logon home` parameter in Samba specifies the path on the Samba server where roaming profiles for users are stored, and it is particularly relevant for older Windows clients like Windows 98 to correctly locate their profiles.

`logon path` is typically used for newer Windows clients (NT, 2000, XP onwards) to define the path to their roaming profiles, using a different format than `logon home` required by Windows 98.

`logon script` is used to specify a batch file or executable to run when a user logs on, not for defining the location of roaming profiles.
