No. It gets the information from /var/lib/dpkg/status. You should run dpkg --get-selections periodically, and keep it on a separate partition, a floppy, or some other safe place. Once your /var is hosed, it's too late to do it. But it's a lot quicker and easier to run dpkg --get-selections than to make a full backup. Bob -- _ |_) _ |_ Robert D.

Can it fetch it, say, from my local mirror? what the --*-selections options do is tell the debian packaging gremlins to save and recall the list of packages you want. when you use dselect (the slink debian way) it does basically this kind of 'these packages are to be installed because the boss says so, and these are to be removed, for the same reason.' you could do dpkg -i some-package-name.here.etc.deb to install each (any) particular package. i'd bet that when you use the old dselect to do the [I]nstall portion, it'd tell dpkg to do just that (and more, probably). but with apt-get these days, you don't have to worry about directly chatting with dpkg; once your selections are set, and your sources.list is alright (use apt-setup for that) just apt-get update and-get upgrade and you're off to the races. right? unless i'm wrong about all this, which means you'll have to learn about it on your own. or at least double-check my say-so. -- also check our handy newbie-friendly links section over at http://www.eGroups.com/group/newbieDoc [EMAIL PROTECTED]***http://www.dontUthink.com/

[EMAIL PROTECTED] (Jim Dennis) writes: (Note: I just try to do an rmdir as the easiest way to detect a non-empty directory *and* to detect a non-directory node named /proc at the same time. Modern versions of mount and fsck allow referring to ext2 file systems by LABEL or GUID (or was it UUID?) in /etc/fstab, so that it doesn't matter if disks or partitions are added or removed. When this is done with the root file system, /proc must be mounted before the root fs is checked because fsck must scan /proc/partitions. Because the root fs is normally read-only at that time, rmdir /proc won't work as a check. Of course, you could unmount /proc again after checking the root fs, but that sounds dirty.
