OK guys. When I bought my ssd, I read too that this story of short 
lifetime is a myth. As it is now clear to me that writing /var/log into 
RAM is a totally fullish idea in case of crash, I am back to my original 
fstab, with no entry for /var/log.
I will then take my time to understand rsyslog or syslog-ng.
Ty all for your wise advises.
