There are various ways to do it, depending on what package management program you normally use. If you use apt-get (and therefore don't keep track of automatically installed packages), you can just use # dpkg --get-selections > dpkg-sel.txt and to install: # dpkg --set-selections < dpkg-sel.txt then apt-get. However, if you use aptitude and were to use the dpkg, you would lose the marking of Automatic or manually installed. As part of my backup script, I run: # aptitude search '~i!~M' > apt_inst.sel I don't know how to tell aptitude to install from this list. I'm on dialup and I wouldn't want it to. I install things in the order in which I need them on a new system; generally in broad categories: ppp, pppconf; mc, lynx; mutt, exim4; vim; etc. > > Why am I not just putting the new motherboard in and trying to boot up? > Becuase others have tried it and reported on the list that the system would > start to boot and then freeze. Well, have your list of installed packages as part of your backup set. Then just try it. If it works, great. If not, it could be that the initrd needs rebuilding; try the install CD in rescue mode. Otherwise, reinstall and restore from backup. Doug. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
