Hello,
I add libhugetlbfs package into my rootfs and run the below command in my board
.
root@p1021rdb:~# hugeadm --create-mounts
hugeadm:WARNING: Unable to add entry /var/lib/hugetlbfs/pagesize-4MB to
/etc/mtab, error: Invalid argument
hugeadm:WARNING: Unable to add entry /var/lib/hugetlbfs/pagesize-16MB to
/etc/mtab, error: Invalid argument
root@p1022ds:~# ls /etc/mtab -l
lrwxrwxrwx 1 root root 12 Jul 31 07:28 /etc/mtab -> /proc/mounts
root@p1022ds:~# ls /proc/mounts
/proc/mounts
root@p1022ds:~# ls /proc/mounts -l
lrwxrwxrwx 1 root root 11 Jul 31 07:58 /proc/mounts -> self/mounts

Could you please detail your environment a little bit?
Where does this error come from?
Besides, if you're going to make this change, please take a read-only rootfs
into consideration. There should be more to fix.
