Kubuntu 26.04 LTS - important things to do after an installation

[wonder]

Hello, short question about the fstab.

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a device; this may
# be used with UUID= as a more robust way to name devices that works even if
# disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
UUID=3CC7-8DA5 /boot/efi vfat defaults 0 2
UUID=08dd13a7-9b53-4073-8ebb-e1fb35e42a42 / ext4 defaults,noatime 0 1
/swapfile swap swap defaults 0 0
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0​

I did not have discard somewhere but I added the noatime. Is this correct?
UUID=08dd13a7-9b53-4073-8ebb-e1fb35e42a42 / ext4 defaults,noatime 0 1

I preferer this:
/ ext4 defaults,errors=remount-ro 0 1

But your noatime (line in your fstab), also, its good.
