well, actually I pressed enter accidentally while typing rm -rf /tmp, which left rm -rf /, which of course isn't good... I was able to stop the process by pressing ctrl-c though, but now my entire /bin directory is gone...I suppose there isn't any way to recover it, is there?

OOops 
Possibly, what FileSystem are you using for your root partition?

If that strategy he would do best to live cd it, mount root and the extract the stage 3 to say /mnt/gentoo/EXTRACT and then "mv /mnt/gentoo/EXTRACT/bin/ /mnt/gentoo/ && rm -rf /mnt/gentoo/EXTRACT" then we just exit and reboot and gentoo should feel well again although I would at least recommend an "emerge -e system" just to make sure everything is alright.

Here is a little Perl program that will tell you which packages you need to re-emerge. It finds every package that has at least one file in /bin/. | Code: | #!/usr/bin/perl -w
use strict;
my $TARGET = "/bin";
my $DB_DIR = "/var/db/pkg";
my (%VALID, %PACKAGES);
for my $dir (<$DB_DIR/*>) {
for my $package (<$dir/*>) {
open(CONTENTS, "$package/CONTENTS") or next;
while (<CONTENTS>) {
m/^(?:obj|dir|sym) ($TARGET\S*)/o or next;
my $file = $1;
$package =~ s{^$DB_DIR/}{};
$package =~ s/-\d(?:[\d.r-]|_p)*$//;
$VALID{$file} = $package;
$PACKAGES{$package}++;
}
close CONTENTS;
}
}
for my $package (sort keys %PACKAGES) {
print "$package\n";
}
__END__ |
Here is the output from my system: | Code: | app-arch/bzip2
app-arch/cpio

You will still need to bootstrap from a stage3 tarball but maybe this will save you a couple of days of re-emerging after you've done the bootstrap. I modified a program I had previously written for finding cruft under /etc/. |
