- Solaris' setgroups(2) doesn't change process' effective gid, so set it
explicitly.
- POSIX doesn't define O_NOFOLLOW. FreeBSD returns EMLINK when target is

- Solaris doesn't define O_SHLOCK and O_EXLOCK flags.

effective group ID or to group ID of its parent directory.
- Add some comments from POSIX.
- Verify that after successful O_TRUNC open, size is equal to 0.
Almost all regression tests are based on very flexible fstest tool.
They verify correctness (POSIX conformance) of almost all file
system-related system calls.
The motivation behind this work is my ZFS port and POSIX, who doesn't
provide free test suites.
Runs on: FreeBSD/UFS, FreeBSD/ZFS, Solaris/UFS, Solaris/ZFS
To try it out:
# cd fstest
# make
# find tests/* -type d | xargs prove
