最近は RAM disk を使っている。特に何が良いか、ということもなく、試している状況。
Cygwin で RAM disk へ cvs co (9分)

で、この場合に、(例えば) G: にマウントされ、cygwin からは /cygdrive/g で見える。これは ssh で他の計算機から入った時にも同じ。

同じように(だと思いたいが) Samba でマウントした状態で、 フォルダにマウスを持って行き、右クリックすると、 「ネットワークドライブ割当」が出て、これで例えば Z: で見えるようになる。
しかし、である。この Z: は、Cygin Terminal の窓からは /cygdrive/z で見える のに、他の計算機から ssh で入った窓では

makoto@m08 

$ ls /cygdrive/
c  d  e  f  g

$ export LANG=C

makoto@m08 

$ ls /cygdrive/z
ls: cannot access /cygdrive/z: No such file or directory

makoto@m08 

$ 

と見えない。これは何故か。見えるようにする方法はあるのか。

• Cygwin installer から util -> screen を入れる
• Cygwin Terminal で screen を起動
• ssh から入った窓で screen -x
