Buglet in mount(8) with large page size

[Nathan Scott <nathans@xxxxxxx>]

Hi Adrian,

We have had this XFS bug report...
        http://oss.sgi.com/bugzilla/show_bug.cgi?id=704
...and Arthur has diagnosed the problem and proposed a fix.

Its in some code we "lifted" from mount(8) to attempt to detect
an existing filesystem/partition/... before overwriting it with
mkfs.xfs.

How do you want to fix this in mount_guess_fstype.c?  Options
would seem to be:
- bump up the size of the "buf" array to cater for all current
page sizes; or
- malloc the read buffer taking into account the page size.

cheers.
