hg commit error in FAT32 file system

[Luo Ben]

Dear All,

I use Debian/Window 2000 in a computer. Now I use mercurial as my
version control system. Because I use W2K and Linux in the same
laptop, so I want to make a repository in a FAT32 file system. So I
can checkout either in Linux or in W2K.

hg init
hg add *

work well.

But after I use

hg commit, the error as below,

-- start screen --
hg commit

Exception exceptions.OSError: (1, 'Operation not permitted',
'/mnt/small/project/automneyes/.hg/.dirstate-H6IEzu') in <bound method
lock.__del__ of <mercurial.lock.lock object at 0xb7d6f54c>> ignored
Exception exceptions.OSError: (1, 'Operation not permitted',

dirstate.__del__ of <mercurial.dirstate.dirstate object at
0xb7a932cc>> ignored
-- end screen --

How can I do?

Best regards,

Ben Luo
