I do see maturity and a great many improvement but I must agree that
comparing the change log to bug reports seems to indicate a level of
instability. There do seem to be a great many bugs that dump core but
this may be the nature of the beast when interacting with the Linux
kernel, a constantly moving target. I'm not one to criticize but if
software in our organization repeatedly produced segfaults, I'd suggest
that developers look closely at improving error traps and handling
and/or analyze faults to see if patterns or trends emerge. Still, there
are enough alternatives and security features in EL to mitigate most
problems.
