base-files-mketc.sh
Having recently installed Cygwin on a new machine, I noticed that the symbolic links to the base files in /etc use Cygwin syntax (/cygdrive/c/). They break when /cygdrive is modified, which is frequently the case on a new install. It would be more robust (and easier and efficient) to use the Windows paths in the symlinks. Pierre

Pierre Pierre, FYI, base-files-mketc.sh uses the `cygpath -u ...` syntax to get the directory. Thus, if your cygdrive prefix is changed *before* the postinstall scripts run, the script should pick up the correct one.

Yes, this seems to work. I guess I just prefer seeing POSIX paths in symlinks... FWIW, I noticed another problem with the `cygpath -u` syntax: if the user has her own mounts for the C: drive, the symlink will reflect that mount, and thus will not work for other users on the machine. For example, I have $ mount | grep user c: on /mnt/c type user (binmode) $ and creating a symbolic link produces $ ln -s `cygpath -u 'c:\WINNT\system32\drivers\etc\hosts'` hosts $ ls -l hosts lrwxrwxrwx1 igor None 154 Feb 3 13:20 hosts - /mnt/c/WINNT/system32/drivers/etc/hosts $ which, of course, will not work for the other users on the machine. So it looks like both of you are right, and we need to use Win32 paths.

We don't need an advanced button, nor do we need to change the /cygdrive/ prefix in setup. What we need is to install correctly regardless of the prefix, and to install in such a way that changing the prefix later will not break things. Fin.
