Using EAs for symlinks predates klibc by years; klibc initially did 
something incompatible, and I was at least one of the people that 
requested it be changed to match.

Never had that problem, but I don't use Ubuntu, nor have I accessed HPFS 
under Linux in recent years.  I wouldn't be surprised if that's a 
Ubuntu-created problem (they tend to do their own thing).

Conversely, the ext2 IFS for OS/2 worked really well for read/write once 
upon a time, but it's incompatible with the ext3/ext4 journaling and 
only works in read-only mode.  Apparently it also has some problems with 
LVM, and some have suggested even read-only doesn't work with partitions 
created with newer tools.

Partition Magic was a really nice tool upon a time; it's too bad they 
dumped HPFS before they added any Linux file system support.  Of course, 
it's all ancient history now, thanks to the devouring beast known as 
Symantec.

Never had much luck with those.

Oops.  :(
