What is the location of the file that needs to be modified to enable filesystem quota support?

The initialization of filesystem quota support in a Linux operating system involves making modifications to the /etc/fstab file. This file is responsible for defining how disk partitions, devices, and filesystems are mounted and configured at boot time.

To enable quota support, specific options need to be appended to the filesystem entries in /etc/fstab. Typically, this involves adding the usrquota and/or grpquota options to the filesystem that requires quota support. These options instruct the operating system to track user and group disk usage on the specified filesystem, thus enabling the quota functionality.

In comparison, the other options do not correlate with filesystem configuration in the same way. The /etc/default directory typically contains default settings for services and applications but does not directly manage filesystem mount parameters. The /etc/sysconfig directory is often used for configuration files related to system services on RPM-based distributions but lacks direct relevance to filesystem quotas. Lastly, /etc/quotas does not exist as a standard configuration file for managing filesystem quotas; rather, quota limits and settings are usually managed through commands like edquota and quota after enabling quotas via /etc/fstab.
