Re: unison doesn't honor HOME when USERPROFILE is set, also permission/uid/gid problems when synchronizing

In that case it will use $UNISON.
According to the file

      \032  Unison stores a variety of information in a private directory on each\n\
      \032  host. If the environment variable UNISON is defined, then its value\n\
      \032  will be used as the name of this directory. If UNISON is not defined,\n\
      \032  then the name of the directory depends on which operating system you\n\
      \032  are using. In Unix, the default is to use $HOME/.unison. In Windows,\n\
      \032  if the environment variable USERPROFILE is defined, then the directory\n\
      \032  will be $USERPROFILE\\.unison; otherwise if HOME is defined, it will be\n\
      \032  $HOME\\.unison; otherwise, it will be c:\\.unison.\n\
      \032  \n\

I can't remember where it comes from, it's to long ago. I can only say
it does.

It did not sync the owners and groups, no errors. And for example if you
have two dirs in sync and now create a new file (umask 0022) in one of
them, then chmod 755 it, your version in my case creates the file in the
other dir with 644 permissions. With my patch it works the sync-ed file
also has 755.
