Well, I don't use webmin or usermin so I can't help much with those, although if you post a stanza to list relevant files I will be happy to add it in.

On the upside, I've just added X.org and ruby support.

To list some of the stuff it's finding:
Code:
/var/www/localhost/htdocs/squirrelmail/data
/var/www/localhost/htdocs/<stuff I added>
/var/spool/postfix
/var/log/*
/usr/share/xplanet/<lots of stuff>
/etc/postfix
/etc/pam.d
/etc/ddclient
/etc/apache2/<keys>
/usr/libexec/webmin
/var/webmin
~/.maildir (my mail isn't cruft!)

16041 files. Some of it is cruft (mostly stuff in /usr/share/doc and /usr/share/man) but most of it isn't.

Added /var/www.
/var/log is managed per-package.
/usr/share/xplanet is handled fine on my machine - have you added some files?
/var/spool/postfix, /etc/postfix are in the ebuild, -r2 at least.
Plenty of ebuilds install into /etc/pam.d.
For /etc/ddclient I need to know what the conf files are called.
Is there a way to know what the /etc/apache2/<keys> files are?
/var/webmin is excluded already - are you sure webmin is installed via Portage?
/home is excluded, so no idea why ~/.maildir would be listed.

Code:

/etc/ddclient/{ddclient.cache,ddclient.conf}

/etc/apache2/conf<domain>.key
/etc/apache2/conf/<domain>.key.unsecure
/etc/apache2/conf/<domain>.key.unsecure.csr
/etc/apache2/conf/ssl
/etc/apache2/conf/ssl/server.crt
/etc/apache2/conf/ssl/server.crt.orig
/etc/apache2/conf/ssl/server.key
/etc/apache2/conf/ssl/server.key.orig


Whoops, I had uninstalled webmin/usermin as I wasn't using them so it was actuall cruft. Thanks again! The ~/.maildir is actually /.maildir left over from long ago I believe. Sorry. Need to find out what that's doing there.

Yeah, I guess all the xplanet stuff is addons from the xplanet site (hurricanes, forecast, images, etc.).

I've got postfix-2.0.19 and it's listing 148 postfix files including /etc/postfix/sample/*.

It seems to be listing everything in /var/log including apache, ftpd, telnet, sshd, pwdfail, kernel, everything, critical.

Down to 2289 files now, most of them stuff I've installed myself or stuff I need to look through. Love this script!

having a little problem with your script, which btw I appreciate.

When I try to run it (as root) I get the following error:
Code:
./cruft: line 513: syntax error near unexpected token `&&'
./cruft: line 513: `    && [ -r /usr/share/baselayout/mkdirs.sh ]'


Any thoughts?

Thanks

Awsome script, I was wondering how to get rid of all my old files for a while now. Things I thought were associated with packages turned out to be cruft. Good job, keep up the good work.

Pretty cool.

It would be nice if it ignored my windows partition which is always mounted... it's listing 30+ GB of cruft under /c. I realise that's a matter of opinion, but the first 37000 lines are from this drive!

cruft ignores a number of toplevel directories. e.g. /opt, /mnt and /media. I mount my windows drive as /opt/windows.

Add a line to the script and tell it to ignore that directory. I added a ton of stuff because there are some things I didn't install through portage.

For some reason it seems to be picking up my squid cache?
Edit:
It also picks up /var/lib/setiathome
I have set it to ignore but, could we not pass in an ignore list, that way we can pick up any updates, without loosing our ignore list

Added, and added. I'm not going to add support for passing in an ignore list because I want everyone to benefit from new exceptions being added.

"For some reason"... it picks up anything that isn't installed at emerge time (and a few things that are, if the ebuild is kludgy) except stuff in directories that don't belong to a Linux system and auto-cleaned temp directories. /var/cache/squid is in /var/cache, so it would get picked up (but not now, of course).

Maybe add a notice that it's meant to just generate a link. Normally a user might want to evade any of these scripts... Shouldn't it be promoted as a 'remove candidate list' generator?

Note that to few false positives can result in (barely) careless people removing just 'a few essential files' and still corrupt their system?

Could you add:
/vmlinu.*
/\.*config\*
/System.map
/
Might be pretty important... :wink:

And maybe consider:
/usr/sbin/gcc-config
*/lost+found/

It's version 0.0.4 (version bump!) Anyone who trusts something this primitive doesn't deserve to be an admin...

These should be in /boot.

Odd... that should handled already. Can you try again with the latest version?
Quote:

gcc-config is in /usr/bin... which version of gcc-config do you have?
lost+found: OK, it now ignores lost+found for each mountpoint, but still flags files therein. Is this OK?

Update: now handles kernel modules (checks for installed linux-sources ebuilds and notes the corresponding directory in /lib/modules) - so now you don't need to worry about remembering to clear out /lib/modules when you update your kernel.

Version 0.0.5.
New packages: xcdroast, acovea, GIMPS, shorewall, acpid.
Now handles /etc/init.d scripts (anything in a runlevel is OK, so now net.* scripts are handled as long as they are in a runlevel).

Interesting... it'd be nice to get some developer love on this.

Anyway, 0.0.6 now. A few things: some stderr status output; more fine-grained over portage, devfs and udev; and faster package version checking code (written in bash by me, much faster than launching Python each time).

nice script, thank's.
but i guess it's a false positive


Code:

/usr/share/wallpapers/
/usr/share/wine/
/usr/share/xine/skins/
/usr/share/xmms/Skins/
/var/lib/nessus/
/var/lib/ntop/

What does /usr/share/wallpapers belong to? If it's yours then it should be in /usr/local.

Is /usr/share/wine your fake windows drive? You'd be better off moving it to /opt/winedrive, or at least /usr/local/share/wine.

Xine: nope, not adding that. Put skins in ~/.xine.

For xmms:
Quote:
# Add /usr/local/share/xmms/Skins to the search path for skins
epatch ${PATCHDIR}/${P}-fhs-skinsdir.patch


OK, added nessus and ntop.

Actually, better would be a xine-themes ebuild. I just posted one, see https://bugs.gentoo.org/show_bug.cgi?id=49959 - hopefully it will be added to Portage soon.

Hmmm... wonder who'll get the 50000th Gentoo bug? Quite a milestone... :D

If you use ccache, EVERY file in /var/tmp/ccache shows up ( 3000+ ), and I wouldn't consider that cruft =)
