Actually SLES9 shipped with IBM dprobes long before Solaris dtrace even
existed (and OS/2 did long before that). Back then the interest in it
was about zero though, which made SLES10 drop it again.
I think I was one of the very few users. Admittedly the early RPN
probes were also not particularly user friendly, but they worked.
I use this always as an example that even sophisticated users
like system administrators and kernel hackers are somewhat marketing driven.
 which BTW already supported user space probes
