No.  EFS is not a very complex filesystem, roughly as complex as for example
UFS.

However later PROMs also know about XFS I think and that's the trivial
case.  Anyway, as afair the EFS CDROMs are partitioned like disks a
bootloader there could also be made to contain something like libext2fs and
boot the rest of a ext2 on the CDROM.  ISOfs if you have a nice library
to use for that.
