Hi, Lorenzo.

Yes, all of functions we need to enable SELinux are available.
In addition, you can enable POSIX ACL support on jffs2.
# But, POSIX ACL consumes memory as much as Ext2/3, I think it's not
# suitable for embedded. So, it should be fixed on 2.6.19. orz

This achievement would not have been possible without collaborating
with David Woodhouse and any other MTD peopel.
The serious of patches are already merged into Linus's git-tree via
MTD-tree and queued for 2.6.18 now.
See,

> Are you using a special policy? Busybox modified?
No, I installed a non-modified Nakamura's policy the small PDA,
because I didn't have enough time for this.
And, busybox is not modified by same reason.
'ps' is an exception. As it didn't work correctly, I installed
a part of the procps package.

Please recomend it to my boss. :)

What kind of modifications for uClibc is necessary, do you think?
Because I don't have enough experimence on embedded region,
any ideaes and collaborations are wellcome!
