有没有人对使用UUID作为密码有意见？这适用于为外部用户创建的帐户,例如客户访问专用SFTP文件夹.或者人们使用公钥代替？这些用户没有
shell并且是chroot到他们的目录.
从联机帮助页：
UUIDs are 128 bit numbers which are intended to have a high likelihood of uniqueness over space and time and are computationally difficult to guess. They are globally unique identifiers which can be locally generated without contacting a global registration authority. UUIDs are intended as unique identifiers for both mass tagging objects with an extremely short lifetime and to reliably identifying very persistent objects across a network.
我使用的是Ubuntu 9.10,但是OSSP uuid软件包适用于大多数* nix发行版.
