Thank you Chavdar for the suggested PRs, with or without the help of 
the AI, the fact is that NetBSD creation and fixing of ext2 filesystems
do not work properly as several people have experienced. Only someone  who understand the ins and outs of the 
operating system could fix it. With my lack of understanding the only thing 
I can do is helping to find bugs. I am not qualified to fill out a PR without understanding it.

Thanks so much.
Ramiro.
