I thought apt-cacher was an improvement on apt-proxy. Boy was I wrong. It’s been giving me a lot of headaches. Whereas apt-proxy needed the odd restart, apt-cacher needs files to be deleted from it’s cache every now and then…
What a pain.
Now I’ve switched back to apt-proxy, and with a bit of squid tweaking (so that local network traffic isn’t cached, or passed to the SAIX proxy) everything is working well again.
I decided I wanted a 64bit kernel for my UK2 server (seeing as it’s an Athlon X2, and I wanted an ubuntu amd64 chroot to work on it).
After a little playing around, this is how you do it:
make menuconfig ARCH=x86_64
linux-amd64-ld, etc. wrappers. Some need
-m64options. Others autodetect what’s required. (I made a tarball of my wrappers, but they’ve been lost.)
CONCURRENCY_LEVEL=4 make-kpkg --append-to-version '-londonpride' --revision '1.00' --rootcmd fakeroot --arch amd64 kernel_image
Unfortunaly, in the week after this, my machine died of disk corruption. This is the 2nd time it’s happened. I hope UK2 don’t use dodgy hardware…
After reading an article about using aptitude properly, I decided that it’s time to make the switch from
apt-get. Sure, on some really low memory systems, running
aptitude isn’t an option, but for most machines, keeping track of which packages were installed as dependancies really helps keep a system trimmed.
I didn’t like the way that the author did it, I opted for a variant of one of the comments:
While rather a monster command, it does a good job of selecting things that were probably installed as dependancies. If you see anything in the list of things to be removed that you want to keep, you just add in an
!~npackagename. Then after that, I run
aptitude, limit to
~i!~M (installed, but not automatically) and mark everything that should be a dependancy with
Then, it’s simply a case of only ever using
aptitude, and your system will be kept nice and clean :-)
Aptitude search patterns are really powerful, instead of having to do the whole
dpkg -l | grep ^r type mission, you can just do
aptitude search '~c'.
