I do use a lot of packages above and beyond the standard install. I also play with lots of others and over time can accumulate a couple of gigs or more of dross that can turn a 1hr upgrade into a 3 hours of download and several hours of install as often it stops to ask if configs should be overwritten and I've invariably fiddled... I've one machine that will bust my monthly download limits by itself so I thought a bit of housekeeping might be in order. Seems the biggest culprit though is Java which seems to think the documentation (about 4 times the size of working code) is essential and when you load two versions you get over a gig of crap you never read...On 10/10/11 18:15, tom wrote:It seems to use the last accessed flag(???) to date when something was last used - seemed to give 'reasonable' results for my machineYes it is using the last inode atime (access time) of any file in the package. The atime attribute is sometimes disabled (mount option noatime) on file systems because it causes an inode update for every (or more recently many) file reads. http://www.unixtutorial.org/2008/04/atime-ctime-mtime-in-unix-filesystems/ I didn't know popcon used it in the reporting, and I'm doubtful how much time it'll save over just installing all the same packages. Of course the other approach is to install what you want, and install any packages you find missing as you need them.
