[clue] Automatic /smb fs, just like /net

The autofs configuration below allows any user to create a .secret.txt in $HOME and then depend on the autofs daemon to perform mounts in the /smb tree using their credentials, like this:
ls /smb/server/share/dir1/.../dirN
$ cat /etc/auto.master
<snip>
/smb /etc/auto.smb.top
<snip>
$ cat /etc/auto.smb.top
* -fstype=autofs,-Dhost=& file:/etc/auto.smb.sub
$ cat /etc/auto.smb.sub
* -fstype=cifs,credentials=${HOME}/.secret.txt,uid=${UID},gid=${EUID} ://${host}/&
Yes, it's got problems and implications:
- root can read that .secret.txt file and get direct access to the user's CIFS credentials.
- a second user on the system trying to access an already-mounted share will be blocked by the previous auto-mount.
... but it's pretty sweet for 80+% of use-cases.
