ALErs -

Last week I upgraded ubuntu-9.04 and now fins the following partition that seems to match my 'root' fs:

~$ df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda1            477762260  49488544 404004724  11% /
 ...
none                 477762260  49488544 404004724  11% /var/lib/ureadahead/debugfs
 ...

~$ mount
/dev/sda1 on / type ext3 (rw,relatime,errors=remount-ro)
 ...
none on /var/lib/ureadahead/debugfs type debugfs (rw)
 ...

What is this 'debugfs' and do I want to keep it around? If not, how do I dump it?

TIA.
