Greetings, Thomas Schweikle!Is it possible to have the same home for Windows and cygwin?See /etc/nsswitch.conf and https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-mapping-nsswitchUsing "C:\Users\<user>" for Cygwin home setting mount points for users?I don't get this question. Can you please rephrase?
I've tried to set C:/Users /home ntfs binary,posix=0,nouser 0 0 Then have "C:/Users/..." and "/home/..." the same.Did not work this way. Starting some shell got cygwin exhaust "Could not create "/home/<user>" -- true: the directory was there already, but cygwin did not notice. Can't tell why. I could switch to /home/<user>, while cygwin couldn't setting $HOME to /tmp. I had success with
mklink /D C:\cygwin\home C:\Users and then setting /etc/nsswitch.conf to db_home: /home/%U this did the trick: cygwin starting a shell works now as expected.One last problem: the owner of the files was not the one expected. Could change him to the expected one using windows tools.
The remaining problems are all git related: git seems to have problems creating symlinks for clones. Maybe this is just a case enabling privileges via GPO for users needing them. Looks like some sources fail to compile if symlinks are not available.
Or is this a bad idea? Or is it something which has some drawbacks you've to decide to live with? At the moment the most ugly drawback is duplication of various data needed within "C:\cygwin\home\<user>" and "C:\Users\<user>". Would be nice if I could overlay both.There's some caveats to using %USERPROFILE% as $HOME, most notable, you have to be careful with overly sensitive programs, like SSH or GPG. Other than that, the noacl flag on the cygdrive mount will cover you for the time being. I.e.:
This was why I tried to mount C:\Users to /home, having two identical directories making ssh, gpg and others happy.
none /cygdrive cygdrive noacl,binary,nouser,posix=0 0 0And usertemp idea is also a good one:none /tmp usertemp binary,nouser,posix=0 0 0
This was helpful. It is a little bit problematic switching users, but it is lots better than having a global /tmp for all users.
