Memory

Use these two settings (which apply to .ifs files only) to specify whether a program's code and data segments should be used directly from the image filesystem (Use In Place) or copied when invoked (Copy). For more information, see the mkifs attribute in the mkifs documentation.

Data Segment
Copy this item's data segment into main memory, or Use In Place to use it directly from the image.
Code Segment
Copy this item's code segment into main memory, or Use In Place to run the executable directly from the image.

Permissions

Use these settings to specify the read/write/execute permissions (in octal) assigned to each item, as well as the item's group and user IDs.

File Permissions
A three digit octal number that specifies the read, write, and execute permissions assigned to files.
Group ID
The ID of the group. The /etc/password file contains the mapping information for the name (the corresponding group name and group number). The root is always 0.
User ID
The ID associated with a user. The /etc/group file contains the mapping information for the user ID (the corresponding user name, user number, and group number). The root is always 0.
