Hi all, Im trying to add some downgradability magic into pacman .Being quite new to pacman code, i need your help to identify the possible pitfalls of my approach before trying something.
What i plan to do is..
In libalpm/remove.c unlink_file() [ I guess remove.c is the only place where we are removing files ]
replace all unlink(), rename() etc with copyandunlink , copyandrename etc which will copy the file first into an archive file package-backup.tgs in cache,then do unlink or rename. Then finally include all the necessary .INSTALL ,PKGINFO ,.CHANGELOG etc and clean up.
So even if i do a -Scc i will have a backup of what was installed on my system and can roll back to the previous state.
And can sombody please point me to some documentation for libarchive apart from the manpages...
This does not make any sense. People who run -Scc don't want to keep any packages because they take space.
