I think it has an important draw back : Its theme is changing its colour cyclically . Any person having chronic illness Vertigo can not endure such continuous colour change . I could not find any place to stop that colour cycling other than to remove PC-BSD and install another operating systems onto its hard disk . In FreeBSD ports system , for me , problem is not the current port system . My idea is to have additional information about ports . For example , when a package is desired to be added by pkg_add , it is downloading the requested package , decompressing it , and saying that it is already installed , and it is not necessary to install it . Instead of this , the following structure ( a more proper one may be suggested , this is only an idea ) may be useful : In the ports , instead of using short names , use after a certain character a signature name of the port : As an example : kde4.version.signature.tbz . In installed systems , always install in directories having that name with signature . When an install is attempted , again use pkg_add kde4 for easiness , not its long name , or kde4.version to select a specified version . pkg_add should compute the signature of the installed port kde4, and check its value to installed signature name . If they are different , the port is destroyed ( install it unconditionally ) , otherwise proper . pkg_add should check port kde4... in ports . If their signatures are the same , it is not necessary to download and install it . For the dependencies , with a port kde4.....tbz , maintain a kde4.....xml listing all the dependencies , in which they may be inspected recursively ( Such lists are displayed in ports related web pages in www.freebsd.org ) . By checking all the related xml files and installed ports in a system , it will be possible to decide installation possibility of a port attempted to be installed without downloading actual port files . In a directory in the system , maintain a subdirectory of ports : Failed_Builds . Into this directory , store names of the packages which failed during building . When a package is attempted to be build , for itself and its dependencies , check that Failed_Builds directory for matching names . If there exists any one of them , do not start to build , because it will not be successfully completed . ( Entries from that directory may be deleted manually to allow build tries , and successful build may check this directory to remove matching entries if it is present . ) This Failed_Builds list is important , because when that information is not used , the same failed build is attempted many times for an install of some packages . Personally , I am not against an additionally available PBI directory in ports tree . Some users may prefer to use them although some packages will be repeatedly stored in different PBI packages and will be downloaded for each of them . Thank you very much . Mehmet Erol Sanliturk
