 Posted: Wed Dec 04, 2002 8:24 pm Post subject: backing up your system profile packages as package files |
 |
|
Here's my attempt at creating a script which backs up all the packages in your "system" profile as .tbzs in the /usr/portage/packages/All directory. Note, that stuff that begins with a * in the file /etc/make.profile/packages is part of the system profile. I am sure you can poke holes at this script, but somebody might find it useful. If that's the case then great. Here's a warning, if this script breaks anything on your system, I'm not liable, so use at your own risk.
| Code: | #!/bin/bash
LOG=/var/log/system-backup-`date +%Y%m%d%H%M`.log
echo "==============================================================" >> $LOG
date >> $LOG
echo "==============================================================" >> $LOG
echo "Backing up packages." >> $LOG
# grep for everything that begins with a *
# remove * at the beginning (and > or = or <, if present)
# remove everything after a hyphen followed by a digit at the end
# translate new lines to pipe character
# remove the last pipe character
export PKGLIST=`egrep '^\*' /etc/make.profile/packages | sed 's/^\*\(>\|=\|<\)*/
/g; s/-[0-9]\+.*$//g; s/ //g' | tr '\012' '|' | sed 's/|$//g;'`
for PACKAGE in `qpkg -I -v -nc | egrep "$PKGLIST" | sed 's:\(.*\):/var/db/pkg/\1
:'`
do
echo "Backing up: $PACKAGE"
echo "Backing up: $PACKAGE" >> $LOG
if ! /usr/lib/portage/bin/quickpkg $PACKAGE; then
echo "Backup of $PACKAGE failed! Exiting."
echo "Backup of $PACKAGE failed! Exiting." >> $LOG
exit 1
fi
done
unset PKGLIST

As you can see it is an off-shoot of the update-step1.sh script from the Gentoo upgrade guide. |
