mount output  looks fine to me:

/dev/sd0a on / type ffs (soft dependencies, local)
/dev/sd0f on /var type ffs (soft dependencies, local)
/dev/sd0e on /usr type ffs (soft dependencies, local)
/dev/sd0g on /home type ffs (soft dependencies, local)


Tried creating a file and login out and back in and it didn't disappear.

And then I checked the contents of .bash_history and now it seems that
is keeping the commands for this evening logins. Maybe it clears the
file after a period of time? As i said 'crontab -l' doesnt show
anything suspicious...

Any other ideas?

Cheers,
Fred.
