A Linux administrator created a new file system. Which of the following files must be updated to ensure the filesystem mounts at boot time?

The file that must be updated to ensure the filesystem mounts at boot time is /etc/fstab. This file

contains information about the filesystems that are mounted automatically by the mount -a

command, which is usually invoked during the system startup. The /etc/fstab file has six fields for

each filesystem: device name, mount point, filesystem type, mount options, dump frequency, and

pass number. To add a new filesystem to the /etc/fstab file, you need to specify these fields correctly

and make sure the mount point directory exists.

The other options are not correct files for controlling persistent mount points of filesystems. The

/etc/sysctl file is used to configure kernel parameters at runtime. The /etc/filesystems file is used to

specify the order of filesystem types used by mount when no filesystem type is given. The

/etc/nfsmount.conf file is used to set options for mounting NFS filesystems. : Persistently mounting
