With today's tree (20061006), ybin fails when trying to update the bootloader
configuration on Apple hardware. 

audit(1160152655.772:5): avc:  denied  { write } for  pid=20949 comm="hmount"
name=".hcwd" dev=hda3 ino=18 scontext=root:system_r:bootloader_t:s0-s0:c0.c1023
tcontext=system_u:object_r:boot_runtime_t:s0 tclass=file

ybin is a shell script which calls hmount; hmount tries to write a state file.
Normally it tries to write to $HOME/.hcwd but writing to /root should not be
allowed by policy. 

ybin was patched to falsify $HOME, causing hmount to write to /boot/.hcwd
instead. The targeted policy is disallowing this.

This breaks kernel updates (and our installer testing) on Apple ppc hardware.
