I don't want to do a install from scratch, just want to re-install everything, but not touching the configuration files. Still I want to re-install all packages already installed in the system. Is there a way to do such re-install through pacman? If so, please let me know.
In the pacman's wiki page (italian translate) [1] there's a procedure that you could do. With this procedure you can install all the package that you have now in the new system after the re-installation of Arch. First you have to do a package's backup
# pacman -Qqe > pkglist
after that you must save the file pkglist in an USB drive or where you want. In the new Arch, browse in the directory that contains the pkglist file and type
# pacman -S $(cat pkglist)
all of your "old" package will be re-install in the new Arch.

Often times it's the user configuration files that mess up a system, so keep that in mind unless you're really confident it's all in the packages themselves. And if you're thinking of reinstalling a la pacman -S $(comm -3 <(pacman -Qq) <(pacman -Qqm)) then remember to put it in a list first, remove them (-Rscn) and then (re)install (-S). This is because some, if not many packages, contain post-remove/install commands that may affect the outcome. -- GPG/PGP ID: B42DDCAD
