It seems kind time consuming for the FDI to run through every installed package with "FDINST remove” prior to doing an install. Also, this would trash any packages that may have been installed from elsewhere. Doing a comparison of each package to what packages will be installed isn’t practical at present. No, fast way at least. Also, there is another issue. When installing a package if one of it’s files exist, the install will fail. All of this would be solved with a simple /overwrite, /force or similar switch was added to FDINST. Even a /force:IReallyMeanIt switch would be nice. > > Mateusz > > > ------------------------------------------------------------------------------ > _______________________________________________ > Freedos-devel mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/freedos-devel > ------------------------------------------------------------------------------ _______________________________________________ Freedos-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/freedos-devel
