:~$ mount

/dev/sda1 on / type ext4 (rw,errors=remount-ro,user_xattr)

proc on /proc type proc (rw,noexec,nosuid,nodev)

none on /sys type sysfs (rw,noexec,nosuid,nodev)

none on /sys/fs/fuse/connections type fusectl (rw)

none on /sys/kernel/debug type debugfs (rw)

none on /sys/kernel/security type securityfs (rw)

none on /dev type devtmpfs (rw,mode=0755)

none on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)

# devices that works even if disks are added and removed. See fstab(5).
