For ext[23] filesystems, the reserved blocks percentage is set to 5% by 
default.  UID 0 (root) is the only user who can use any of the reserved 
blocks.  So root could create whatever temporary files were needed but 
a normal user couldn't.

See above.  If you only have one partition, you should *NOT* set the 
reserved block percentage to 0%, but if you have /home, /var, /usr, 
and /whatever , you can set the percentage to 0% on everything but /var 
and / .  5% may be too much for large filesystems, but in your case I 
wouldn't go below 2%.  "man tune2fs" for info on how to change the 
reserved block percentage.

No.
