<div id="body1550126534609"><div class="section" id="sfs_01_0100__section15512154184412"><h4 class="sectiontitle">Scenarios</h4><p id="sfs_01_0100__p1912322155117">By default, a Linux ECS allows only the <strong id="sfs_01_0100__b695718159484">root</strong> user to run the <strong id="sfs_01_0100__b202391386132">mount</strong> command for mounting a file system. However, if the permissions of user <strong id="sfs_01_0100__b995119314482">root</strong> are assigned to other common users, such users can also run the <strong id="sfs_01_0100__b2851151412136">mount</strong> command for file system mounting. The following describes how to mount a file system to a Linux ECS as a common user. The EulerOS is used as an example.</p>
