Can etckeeper be used to track config files outside of /etc?
Solution 1:
I edited the above script to also include plain files.
maybe someone should add a possibility to configure this outside a script (in the etckeeper config?) and send this as a patch to joey hess?
#!/bin/sh
set -e
# Based on nealmcb's + ErebusBat's script from http://serverfault.com/questions/211425/
# If you want other configuration data or files on the system also
# opportunistically tracked via etckeeper, use this script to copy them in.
# If there is a hook of some sort available related to the files
# you're mirroring, you can call etckeeper directly and track them
# proactively, rather than just opportunistically here.
MIRROR_ROOT=/etc/etckeeper.mirror.d
echo "etckeeper: mirroring outside files to $MIRROR_ROOT/:"
mirror_dir() {
LOCAL_PATH=$1
echo " $LOCAL_PATH"
mkdir -p $MIRROR_ROOT/$LOCAL_PATH
rsync -a --del $LOCAL_PATH/ $MIRROR_ROOT/$LOCAL_PATH
}
mirror_file() {
LOCAL_PATH=$1
DIRPATH=`dirname $LOCAL_PATH | head -n 1`
echo " $LOCAL_PATH"
mkdir -p $MIRROR_ROOT/$DIRPATH
rsync -a --del $LOCAL_PATH $MIRROR_ROOT/$DIRPATH
}
mirror_file "/var/srv/foo_bar/blog/config.py"
mirror_file "/var/srv/foo_bar_another_host/trac/conf/trac.ini"
mirror_file "/tmp/wildcards/*.jpg"
Solution 2:
etckeeper does allow you to integrate it with other systems.
I also wanted to track changes made by update-grub in /boot, so
I put the code below in /etc/etckeeper/commit.d/20mirror-outside-files
This way any time etckeeper is called for other reasons (when I install software, sometimes nightly, etc), it will grab and track revisions in the latest grub configuration.
I invented the convention to put this stuff under /etc/Mirror/path-to-outside-file, e.g. /etc/Mirror/boot/grub/grub.cfg
but if anyone has precedent for another such convention, I'd love to hear about it.
#!/bin/sh
set -e
# If you want other configuration data or files on the system also
# opportunistically tracked via etckeeper, use this script to copy them in.
# If there is a hook of some sort available related to the files
# you're mirroring, you can call etckeeper directly and track them
# proactively, rather than just opportunistically here.
echo etckeeper: mirroring outside files
mkdir -p /etc/Mirror/boot/grub
cp -p /boot/grub/grub.cfg /etc/Mirror/boot/grub
Update:
Note that for some reason etckeeper doesn't run this when you do an apt-get remove or purge, e.g. to delete an old kernel. Odd.... But you can run sudo etckeeper commit
manually in that case, or after a manual update-grub
.
Solution 3:
etckeeper now has a -d
option to indicate on which directory it must operate.
While hooks to trigger etckeeper generally use construct as etckeeper pre-install
, ..., you will have to add hooks that use etckeeper pre-install -d /boot/grub
instead. This shall avoid file duplication in your approach.
Note that if you consider that systemd target, service, ..., files are configuration files (I do - after all, files under /lib/systemd
are not that different from files under /etc/init.d
) then this -d
option will help you to keep track of what happen in /lib/systemd
