Re: Clean rootfs

Ouch. After:

dpkg -l | grep ^rc | cut -d " " -f 3 | xargs dpkg --purge

my free rootfs space went from 30.6 to 29.4!?! Any idea what went wrong or where the missing 1.2mb is from?

Re: Clean rootfs

@szopin,

LOL :) Could be that the dpkg log (I suppose there's some log somewhere) grew more than the config files that were deleted :)

Are you sure you measured free space right before and after the dpkg command?

Re: Clean rootfs

Yeah, was doing steps from this thread and checking 'df -h /' after each. Strangely enough microb-engine gave me only ~7mb and microb seems to start up faster (compression on rootfs?). Now to find that dpkg log, if it grew by 1mb and is on rootfs optifying that should give lots more free space...

Re: Clean rootfs

Got it:
rm /var/lib/dpkg/*old
should be executed last, or new -old files get created.

Re: Clean rootfs

I followed these instructions and now my media doesn't play in open media player or the regular media player. As a matter of fact my media played shows 'No music', 'No videos' etc...

Opera stopped working past log in prompts etc...

Free up rootfs space

YMMV...

here are most lines...

Code:

rm /var/lib/dpkg/*old

mv /usr/share/nokia-maps /home/opt/

ln -s /home/opt/nokia-maps /usr/share/nokia-maps

mv /usr/share/microb-engine /home/opt

ln -s /home/opt/microb-engine /usr/share/microb-engine

mv /usr/share/fonts /home/opt 

ln -s /home/opt/fonts /usr/share/fonts

mv /usr/share/locale /opt

ln -s /opt/locale /usr/share/locale

mv /usr/share/themes/ /home/opt/usr/share/themes

ln -s /home/opt/usr/share/themes /usr/share/themes

dpkg --purge tutorial-home-applet 

dpkg -l|grep ^rc

last command has been rewritten by Joseph9560 as

Code:

dpkg -l | grep ^rc | cut -d " " -f 3 | xargs dpkg --purge

nota bene: moving & relinking the theme part means you can't install any new themes unless you delete the link & move the files back to their original place...

i use those exact instructions routinely when reflashing my N900s (now mostly the test model :cool:) and never had any problems
then again, i don't give a darn about themes :rolleyes:

I've typed this (as root):

apt-get autoremove

my free rootfs increased by 8% but before I recommend to try this:

apt-get --simulate autoremove

this command simulates the autoremove action so, you can check the output in order to be sure that only useless packages will be removed.

Try also: apt-get moo

This won't help you in rootfs cleaning but is absolutely safe! ;-)

how exactly do i use these things?

Re: Clean rootfs

If you used some Application Manager to install or remove packages, there is no need for the autoremove, because that is invoked by those Application Managers.

If you did not use the Application Manager, but apt-get in X-Terminal you could use the command as root to erase the downloaded installable packages after the installation.
