3-4. Linux FileSystem Basics Linux FileSystem Conventional disk filesystems: ext3, ext4, XFS, Btrfs, JFS, NTFS, vfat, exfat, etc. Flash storage filesystems: ubifs, jffs2, yaffs, etc. Database filesystems Special purpose filesystems: procfs, sysfs, tmpfs, squashfs, debugfs, fuse, etc. Partitions and Filesystems A partition is physically contiguous section of disk, or what appears to be so in some advanced setups. A filesystem is a method of storing/finding files on the hard disk (usually in a partition)....

Kernel, init and Services The Linux Kernel boot loader loads kernel and an initial RAM-based file system (initramfs) into memory, so it can be used directly by the kernel. kernel loaded, it immediately initializes and configures the computer’s memory and also configures all the hardware attached to the system. also load user space applications. /sbin/init and Services Once kernel has set up all its hardware and mounted the root filesystem, the kernel runs sbin/init....

The Boot Process The Linux boot process is the procedure for initializing the system. from when the computer power is first swithced on until the user interface is fully operational. having a good understanding of the steps in the boot process may help you with troubleshooting problems, as well as with tailoring the computer’s performance to your needs. On the other hand, the boot process can be rather technical, and you can start using Linux without knowing all the details....

Learning Objectives Identify Linux filesystems. Identify the differences between partitions and filesystems Describe the boot process. Install Linux on a computer.
