   I figure each distro's boot loader will support that distro's own   
   recommended filesystem.  I'll have make sure each one I install can r/w   
   ext4 on other partitions, and also what's involved in converting an ext3   
   partition to ext4.  Most of my data directories are still ext3.  In my   
   case another consideration would be my external USB HD.  One partition   
   is VFAT and has programs for both Windows and Macs to read the files in   
   my ext3 backup partition and un-tar them.  My purpose was that, if   
   necessary, I could connect the external HD to anyone else's computer and   
   copy my backups to a flash drive.  (Maybe it would make more sense to   
   just have my backup partition be VFAT, but I'd still need programs for   
   Windows and Macs to handle my .tar.gzip backup files.)

   Interesting point.  I'll see whether there's anything about that on the   
   web.  I was just mucking about in my /etc/fstab after repartitioning to   
   fit more distros on my internal HD.  I also learned /not/ to list my   
   removable devices (all VFAT flash drives, some of which are MP3 players)   
   in fstab, so Mandriva 2010.0 will automount them using the partition's   
   volume label.
