Steve,
I thought the cygwin heap was, in essence, that virtual machine - it stores persistant data across invokations. All that needs to happen, as far as I can see, is for the setuid/seteuid/etc/etc calls to set per-process values in the shared memory heap and for getuid/etc... to use that value. The "uid" concept is completely lacking in Win98, so cygwin's spoofing that already.

I'm no Cygwin developer as of yet, but I think I can answer this one.
Cygwin, for the most part, provides a 'nix wrapper around Windows, and
uses Windows to do the work.
NT allows separate processes to run in different user contexts, but Windows
98 does not. Thus, Windows 98 has no applicable functionality to wrap.
You would need an entire virtual machine with another copy of Windows
running another Cygwin to do what you're talking about.

Alex,
Thanks for your thoughts. Unfortunately, this doesn't fool any programs that use getuid (or id.exe, etc) to work out what settings to use. It'll get around one or two things, but so many unix utils know about getuid and getpwent to find a user's details, it falls apart..! :-)

It sounds like what you want to do is just have different user
'sessions' run by Cygwin. Cygwin uses your /etc/profile file, among
others, to determine who is logged on. You could modify the batch file
that launches the shell to be something along the lines of:
if %1x==x then goto end
if %1==foo then goto foo
if %1==bar then goto bar
goto end
:foo
cd \cygwin\bin
del /y ..\etc\profile.
ren ..\etc\profile.foo profile.
bash --login -i
goto end
:bar
cd \cygwin\bin
del /y ..\etc\profile.
ren ..\etc\profile.bar profile.
bash --login -i
:end
It's been a while since I've changed my preferences, and I'm sure that
there's at least one thing that I'm missing in addition to the profile,
but hopefully the above at least gives you a place to start from.
Assuming that your foo profile had your username set to foo and your
HOME set to /home/foo, and your bar had your HOME set to /home/bar, you
would have your individual profiles to work with within those
directories. (i.e. /home/foo/.bashrc)

Subject: Win98 and multiple users
I'm not sure how this request will be taken...
I want to get cygwin to support multiple concurrent _different_ logins
under Win98. I want to have one window logged in as user_a and another
logged in as user_b.
From reading the archives and website, I can see no _technical_ reason why
the cygwin heap can't keep track of separate users (after all, it does
exactly that on WinNT). Equally, I can't see what I need to tweak to get
it to work on Win98.
(If Win98 users were really different users, there would be security
implications here. However, all I really want to do is organise different
collections of preferences for my different work mode - without having to
log off Win98 to switch.)
Can anyone give me some pointers..?
