Description

If the --dry-run option is used, the syntax checking allows --hsm-root to be omitted, which implies that the HSM root won't been dereferenced if doing a dry run. This does not appear to be the case.

In particular, the command:

$ lhsmtool_posix --max-sequence --dry-run /lustre

will segfault. Other instances look like they will have the same problem.

The check in ct_parseopts() that reads:

if (!opt.o_dry_run && opt.o_hsm_root == NULL)

should simply remove the "!opt.dry_run &&" clause. All valid operations require that the hsm root be specified.
