# If we invoke this script from the top zrepl source tree, like so:
#    ./platformtest/logmockzfs/logzfsenv ...
# then dirname is relative, i.e., ./platformtest/logmockzfs.
# If we put that relative dir in PATH, then Go >= 1.19 will refuse to
# exec the `./platformtest/logmockzfs/zfs` wrapper script if it finds
# it via PATH lookup. For Example:
#   cmd := exec.Command("zfs")
#   err := cmd.Run()
# will fail with an error that errors.Is(err, exec.ErrDot), message:
#   cannot run executable found relative to current directory
# The solution is to use an abspath.
