In Yast Partitioner, when formatting a partition as ext3, there is an option
described as 'Percentage of blocks reserved for root'. The default value is
'auto' = 5%

What does this mean? Is 5% of the partition not available to an ordinary
user?

Bob


That is correct. The 5% is reserved for logs that get too big or root,
more correctly so root can log in and create his login temp files while
working to free up space. This number can be changed but never change it to 0.


Quite so. I have on occasion noticed that root could log in, while mere
mortals couldn't. It was usually caused by the partition holding /tmp
getting full.
