If this works perfect, then what is the rationale for needing a library? Do you see a clear reason aside from any vague "it's supposed to be that wa= y". In the Unix land it is perfectly normal for programs to call other self-contained programs to do their self-contained jobs: http://www.catb.org/esr/writings/taoup/html/ch01s06.html#id2877684 Not everything must to be a library linked into your main executable, some separation and calling external programs to do stuff such as mkfs or snapsh= ot management seems perfectly fine and even better from the debug-ability standpoint. --=20 With respect, Roman --Sig_/rATqaAf4aODp28JgTy6Yiwh Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iEYEARECAAYFAlVoeDsACgkQTLKSvz+PZwiBiQCgh4nE/xa7ztSMHGRT/8OdjSCB +kAAn0jH86ewwpcLFukZzDINTbb8I4yW =lvEu -----END PGP SIGNATURE----- --Sig_/rATqaAf4aODp28JgTy6Yiwh--
