I've found that keeping "snapshots" of my package state lets me roll
back complicated system state changes.
For instance, this script will list the names of all installed packages:
grep -E "^Package|Status:.+$" /var/lib/dpkg/status | \
sed "s/Package:/\tPackage:/" | tr \\n \\t | sed "s/\t\t/\n/g" | \
grep "install ok installed" | \
sed "s/Package: \(.*\)\tStatus: install ok installed/\1/" | sort
You could run this before and after a "big change" and diff the results.
I won't bother to explain this but this script lets me roll back just
about any complex set of system state changes (it keeps logs of the
state and all the old debs in an organized way):
cd /mnt/apt
cd latest; if [[ `ls *%* 2>/dev/null | wc -l` -ne 0 ]]; then for x in
*%*; do mv $x ${x/[0-9]\\%3a/}; done; fi; cd ..
echo Scanning Packages...
dpkg-scanpackages latest /dev/null > $sub/Packages
grep -Ex "Filename: latest/.+" $sub/Packages | sed "s/Filename:
latest\/\(.*\)/\1/" > old/L$dt
pushd $sub
rm Packages.gz
gzip Packages
popd
mv latest $dt
mkdir latest
for x in `cat old/L$dt`; do mv $dt/$x latest; done
if [[ `ls $dt | wc -l` -eq 0 ]]; then rm -r $dt;
else echo $dt `ls $dt | wc -l`; mv $dt old; fi
