2个小时前收到一台workstation
刚上手UNIX，用root登陆
想建几个用户，却发现home目录是只读的
怎么办？我用file manager想改一下
好象改不了，这个是怎么回事？

1. what kind of machine/OS is it? type
uname -a
to find out
2. If it is a Solaris machine, then autohome manages
/home directory is auto nfs mount of a directory
at somewhere else. Check /etc/autohhome.

你用的什么Unix系统呢? 不同系统可能不一样.
比如说 useradd 或 adduser,

Joking la.
Just want to confirm that doing things with root privilege should be with
caution.

df /home to check out. It's probably a NFS filesystem.

If it runs Solaris 2.X, it might be using autohome. Check
/etc/auto_home.
Modify to disable this, and mkdir by hand. HTH.

Okay, it must be the auto_home thing. Modify /etc/auto_home

automountd is implemented on top of NFS. It's actually a local NFS server.

Well, this is right. You probably can modify
/etc/auto_master file to make
/home not automounted. Just comment out a line like this:
/home /etc/auto_home
You should be able to do what you want.

Then the /home directory will be gone. This is pointless because you still
can't use it. Oh, unless you move everything from the real mount point to
/home afterwards, but why bother? /home is convenient and you should use it.
If you don't want to use it, play with the real mount point (probably sth
like /n/xxx/u/xxx, I am not sure of automountd because we are using amd)
directly.

Okay, I've seen enough and got tired :)
Here is the purpose and advantage of autohome and /home directory.
That is, you can have anybody, to have a home directory under
/home/username
or
/home/dept/username
yet these users/dept expand many drives/directories.
This is not possible w/ conventional NFS mount. The advantage is
the convenience, so you one wouldn't need to modify /etc/passwd
each time one needs to expand the harddisk and change directories
(which can be a pain for NIS

It wont be created automatically, but you can mkdir it which
is what this brother
wants to do initially. As a single user with local disk (I
guess this is the case),
you probably dont need the flexibility of autohome. Anyway,
it is what I did for
my sparc box at home.
