Any even for large ISP mailservers xfs and reiserfs are still huge wins over ext3. Also our 'totally corrupt filesystems' statistics are much higher on ext3 than reiserfs so given all the above we've stopped deploying ext3 in new servers and only deploy reiserfs in new servers now. A pity selinux doesnt work on reiserfs yet, but selinux has serious growing pains atm so we will wait for selinux to stabilize before we worry about that. ext3 might be just dandy for desktops which I expect is the primary target market for fc3/fc4 but reiserfs/xfs are much better for typical ISP workloads. -Dan
