My ~/.profile sufficiently OS-independent, that this works under Cygwin/XP and on any of the various Unixes we run. Great so far. > I didn't think that Cygwin paid attention to the home field in /etc/passwd. Mine does, but that's because I modified /etc/profile to set $HOME based on /etc/passwd's home field. Also, I use mounts instead of mapped drives or even UNC paths in /etc/passwd. So I do a: $ mount -bsf /// /us Note that I use /us for US and /china for China here at work since we have another office in China. Then I modify /etc/passwd to have /us/ for home and remember that /etc/profile has been modified to set $HOME to the home field in /etc/passwd (e.g. /us/adefaria). >One of the Cygwin components installed was SSH.

However I just tried an ssh passwordfull login and mapped drives are listed as Unavailable!

Unfortunately, since the drive I want to map is my home directory, and path to this (as it appears on the PC) is written in /etc/passwd, and I can't/won't change /etc/passwd for each concurrent SSH I start, the solution must be one which makes the drive have a consistent mount/access point under XP. > >Also note, that the shell tries to put me in that home *before* /etc/profile or ~/.profile are run, so some sort of 'net use //server/path; ln -s ....' in /etc/profile probably isn't going to cut it. > >Does anybody know the 'correct' solution to this problem?
