So I have Suggests: 1 - I don't have bluetooth on my machine -- I uninstall the bluetooth stack. - I install a new calendaring program which has the ability to sync with a cellphone using bluetooth. The package has a "Suggests: bluetooth-stack" type thingy. That reinstalls the bluetooth stack. - I uninstall bluetooth. - I upgrade the calendaring program and the package manager sees suggests again -- it reinstalls bluetooth. - I uninstall bluetooth. - Repeat. Perhaps the dep solver would have to keep track of which suggests it has already installed once. [Package] [suggestion] thunderbird libimap-client - Install evolution which suggests bluez-libs; install bluez-libs as well. Add it to the dep solver's db. [Package] [suggested] thunderbird libimap-client evolution bluez-libs - On update, the dep solver sees that it has already installed bluez due to suggests and doesn't attempt to add it to the transaction again. - On another update evolution has added a suggests for a new library; install it and add it to the dep solver's db. [Package] [suggested] thunderbird libimap-client evolution bluez-libs evolution libpop-client - Decide we don't want libpop-client, uninstall it - On update, thunderbird adds a suggests for that library; See that it's already been used as a suggests so do not add it to the package transaction. Do add it to the database. [Package] [suggested] thunderbird libimap-client evolution bluez-libs evolution libpop-client thunderbird libpop-client - Uninstall evolution removes all the dep solver's entries with evolution as Package: [Package] [suggested] thunderbird libimap-client thunderbird libpop-client -Toshio
