Yes and no.
Unix (and Linux) developers are far too concerned with clinging to the 30-year-old outdated POSIX standard, which creates numerous problems when trying to advance new features. For example, the POSIX standard is the reason we have the three-by-three secure permissions on files (three users: owner, group, everyone; three permissions: read, write, execute) instead of Access Control Lists (ACL's).
This is not a design flaw per say, but let's face it: Unix would be a lot more secure (and more flexible in it's security) with ACL's.
Microsoft Windows has had ACL's since 1991 (Windows NT 3.5?); that was 11 years ago. Linux is just now developing ACL's in some of the beta kernels. (By "Linux" I mean the official Linux kernel as distributed by www.kernel.org not these stupid add-on's and patches released by third-parties)

I don't know of any mistakes per say, but if I had to do it over again, there's about a thousands things I'd do differently (preference in design choices, not mistakes) especially not to cling so religiously to POSIX compliance.
