On commanding

#mount /dev/sda6 /mnt/new_root

in order to mount an external usb hd in a pivot_root install of knoppix 5.0.1 I got the message:

EXT3-fs warning: maximal mount count reached, running e2fsck is recommended

sda6 could be mounted nonetheless and I see what I wanted to see: libmotif3 for unstable, which I wanted to install in place of the Sarge version. The latter does not allow openmotif to function. At this point, however, I prefer to wait:
CHANGED MIND BECAUSE, KNOWING MOTIF, I WAS NEARLY SURE TO HIT GOLD: in fact, with the library for unstable my molecular modeling package runs beautifully like in Etch

I know to be with pivot in "uncharted waters" and I also know that running e2fsck on mounted devices requires special expertise and is in any case a risk.

Suggestions? THAT PROBLEM REMAINS AND I CAN ADD THAT SDA6 IS CONNECTED ALSO WHEN ON ETCH, USING IT FOR BACKUP; IMPLICITLY, FILESYSTEM EXT3. BECAUSE IT SEEMS THAT EVERYTHING CAN BE DONE WITH PIVOT_ROOT, THAT STORY OF "MOUNT COUNT" IS DISTURBING.
