making more disk space on ASUS eee 901

I've  had an ASUS eee 901 since they were produced ( preceded by a 701). Initially running Linpus linux that it came with , that got replaced with Ubuntu NBR ( now Ubuntu NBR). And NBR works well. The screen height/width ratio is different and putting the menu along the side makes maximum use of the  available area.

I formatted the flash disks as ext2 - not journaled, decreases the read/write to the disk -  and installed the OS on the 4GB disk and used the 16 GB disk as /home.
This has worked well, except that space became a problem on the 4GB partition. For instance , I had to do updates in steps,  one application at a time.

So Google is your friend and I ended up here and moved /usr/share to the other disk.  As predicted , the firefox icon disappears. But there is a bigger problem. this machine is my travelling companion and I have LAMP installed on it. After moving /usr/share , MySQL didn't start and the log is filled with this , occuring every 10 seconds or so

It wasn't a permissions problem. With the help of the Tyneside LUG, this was fixed . The files were moved, but instead of a symlink, it was mounted using /etc/fstab

/home/.fs-ext/usr/share    /usr/share    none    rw,bind  0 0


and everything now seems to work.
