Thank you for explaining :-) So it looks that it would be sensible to
force filesystem check every n-th mount..? Or to do a filesystem check
after crash..? Are there any flags like that to mark filesystem
unclean and to force fsck after n-th mount? That would assume
disabling journal and soft updates journaling I guess..?

What would be the best option for best data integrity in case of
crash? That would be helpful for development systems I guess :-)
