ext3 Filessyten in FC5-Test incompatible with other FC or RHEL versions

["Dr. Günter Schmidt" <gsc news online de>]

I have a multi boot system with FC5-TEST, FC3, RH9 and Centos4 (RHEL4
clone).
The /boot and /home are common to all OS's. Since I installed FC5 I can
not access anymore
the common partitions if I boot into the older systems.
Is there any solution to that problem.

Any help is welcome,
thanks
 Günter
