It seems that I will need to require admin or root privileges in the
installer, but I'd like the files being installed into the users
library to be owned by that user NOT root or admin. Is it possible to
do this by adjusting settings in my Packagemaker project or through
the use of a postscript installer. I already have some postscript
functionality for moving the files into the User's home library from a
temporary directory, but setting the permissions for these files to
the users is proving harder. Is there a unix command to chown files to
whatever the currently logged in user is? And how might that command
be affected by running the installer as admin or root?
Well, since you know where the user home folder is ($User), this means
the only missing information is the group name. Depending on the OS
version, it's either staff, admin or $User, or wheel.
To do this more cleverly, you could run a ls command on the user home
folder, it will provide you with the name of the group and with a
little help from awk you should be able to retrieve the group name for
the user.
Of course, you can also write your own tool to do this. You could for
instance get the information from Open Directory and use the BSD API
(the Carbon APIs are not working correctly most of the time as are the
Cocoa APIs).
