What evidence do you have that FreeBSD represents as much as 1% of the UNIX market?

No. The 99% figure has to do with using .lock files and permitting NFS access. Linux has a different problem. They want all mail readers to run with privileges. > What is considered 'system call locking'? fcntl *and* flock, or one > of them? or...? Either fcntl or flock. > Both Linux *and* Solaris 2.5.1 support both, if that is > the case... The operating system support isn't the issue. It's what the delivery agents use. The delivery agents on Linux and Solaris use .lock files, not system call locking. > right, so now SVR4, Linux *and* FreeBSD break IMAP Actually, no. Some of the SVR4 and Linux guys run it with SGID mail, although I discourage them from doing that.
