What Linux Beginners Must Know (Part 8 - filesystem mounts and fstab)
In this video we will create a filesystem on a disk, mount the filesystem via fstab using the UUID as a solution for changing devicenames.
Filesystem types:
ext2 Early Linux filesystem, no journaling
ext3 Journaling extension of ext2
ext4 Modern default for many distributions, journaling
XFS High-performance journaling filesystem
Btrfs Advanced features, copy-on-write, snapshots, checksumming
F2FS Flash-optimized filesystem
JFS IBM’s Journaling File System
ReiserFS Journaling, deprecated and removed in Linux 6.13
Reiser4 Successor to ReiserFS, experimental
Bcachefs Next-generation, copy-on-write, experimental (Linux 6.7+)
NILFS2 Log-structured, continuous snapshottin
Default mount options:
rw: Mount the filesystem read-write.
suid: Allow set-user-identifier or set-group-identifier bits to take effect.
dev: Interpret character or block special devices on the filesystem.
exec: Permit execution of binaries.
auto: The filesystem will be mounted automatically at boot or when mount -a is used.
nouser:Only root can mount the filesystem.
async: All I/O to the filesystem is done asynchronously.

defaults = rw, suid, dev, exec, auto, nouser, and async
