[9fans] can any user create files as bootes?

[YAMANASHI Takeshi <uncover@beat.cc.titech.ac.jp>]

If a user login but the home directory doesn't exist,
the user lands on somewhere like /usr/bootes and the
user seemingly keeps the permission of bootes.
But the user looses the permission once he have issued
a `cd' command with an absolute path as its argument.

Does this just happen only on my plan 9 system?


I attched the transcription:
