root partition mounted:/dev/root on / type ext4 (rw,relatime,barrier=1,data=ordered)


after restore from clonezilla (old disk crashed & replaced with new same size ) .
Partition restored according to clonezilla info was ext4 .
#cat /etc/fstab
....
/dev/root on / type ext4 (rw,relatime,barrier=1,data=ordered)
/dev/sdb4 on /usr type ext4 (rw)
....
Both partitions are ext4 why /user is (rw) and /root is so complicated ?
Can i leave it like this or i must correct it ?
How can i correct it ?

Seems that something just copyied the output of the mount command into the fstab .
Code:
man 5 fstab
would tell a little about the syntax .

The "on" , "type" and "("'s shouldn't be in there .

What is complicated . Do you mean the many "Filesystem features" ?

If you don't want to experiment use "auto" for the filesystem .

For documentation on the available options for non-
nfs file systems, see "man 8 mount"(8)

/dev/root is a sym link. I think the information in /etc/fstab should be to the actual phyiscal partition. For example:

/dev/sda3 on / type ext4 (rw,relatime,barrier=1,data=ordered)

I think udev creates the /dev/root sym link.
