I opened the file /etc/fstab and found the following entries only:
proc /proc proc nodev,noexec,nosuid 0 0
/dev/sda5 /boot ext4 defaults 0 2
/dev/sda6 none swap sw 0 0
At the same time I opened the /proc/filesystems file it is having the following entries:
nodev sysfs
nodev rootfs
nodev bdev
nodev proc
nodev cgroup
nodev cpuset
nodev tmpfs
nodev devtmpfs
nodev debugfs
nodev securityfs
nodev sockfs
nodev pipefs
nodev anon_inodefs
nodev devpts
ext3
ext2
ext4
nodev ramfs
nodev hugetlbfs
nodev ecryptfs
nodev fuse
fuseblk
nodev fusectl
nodev mqueue
nodev binfmt_misc
Can somebody please explain me Why all these entries are not present in the /etc/fstab file?
