We really don't know.

Currently, Condor is mostly distribution-agnostic - our dynamically-linked
binaries just ask for glibc, so running Condor with just vanilla, Globus, and
Java universe jobs usually just works on any given distribution.

Where we're most sensitive to different Linux distributions is in the 
checkpointing and remote system call code. Portions of that code are written 
in C++, and require us to link with C++ support libraries and conform to the 
C++ ABI that the compiler is expecting. Sadly, the past couple of Redaht 
releases have all changed the C++ ABI in each release and made our life 
difficult. We're also sensitive to the glibc on the machine, since we need to
catch all file-access calls to convert them into remote system calls, and the
C library has a number of entry points that are sort of "hidden" that take
a while for us to find and code for.

The last thing big that will get us are entries in /dev that represent the 
keyboard and mouse - some distributions use devfs, some dont, and so forth. 

As for Redhat Fedora, we're still scratching our heads. If I had to guess
now, I'd say that's what our main "supported" distribution will be, because
I think that's where most of our current users will migrate to. Over the 
next 6 to 8 weeks I think the we'll start to get a better picture of where 
people are going, and we'll try and keep people informed of what our plans
are.

Thanks,

-Erik
