How to display result of df every 30s?
All I want to see is the % after I issue df / every 30s but on the same line just after the previous number.
So the final output would be 86% 86% 86% 87% 87% ......
Could it be one line code? Or multiple line 'program'?

Is it possible to tell df to use /proc/mounts instead of /etc/mtab?
Installing gentoo in chroot I found that commands like mount and df doesn't work: they try to read file /etc/mtab (which of course is empty).
Can I (for future use) setup or even recompile them so, that they won't read /etc/mtab, taking all needed…
