Anyone know what Used/Avail should be after a clean flash, not installing any apps? Any general 'benchmarks'?

I happened on this thread because I am looking for creative ways to optimize space on rootfs (excuse the pun - or not :-)

My N900 and I go back to November now. I've always kept a watch on rootfs. I've done plenty of re-flashing to clean the slate and start fresh since I test a ton, have been known to download from testing and devels to check out what's in the pipeline and re-flash when I want things stable again or just a clean slate. Until a couple weeks ago when I finally decided, "OK, now it's sterile run time with ZERO anything from testing/devels, no apt-get install, purge packages/libraries that get orphaned during a re-flash, etc."

In summary, before my update to PR1.1 but after a fresh flash and update to the pre-update update the day before (not a single app installed other than what comes with the firmware), I had 72% used.

The next day, after a day of very little other than playing with BT to see if that was handled, PR1.1 popped up. Cool! BT savior! I skimmed some change log somewhere (or it might have been the maemo forum) and noticed it was said to free up some space on rootfs. I think the number I read was it gave you back 20-50MB - don't recall exactly.

Finished update, a couple restarts, a shutdown, battery pull for an hour for good measure, blessed catalogs are all I had enabled (so a total of 4), and I was at 76% used even after an autoclean/clean. What the what?!?!

I figured I would worry about looking for info on this later. So, here I am, a week or so later. I have been fairly busy so my hobby, fun phone I haven't done much of anything with other than calls has now gone from 76% to 81%. Now that's a WTH.

I haven't installed anything, have very little installed in general: AdBlock Plus, AP News widget, FB widget/uploader, Foreca, OpenSSH (c&s), rootsh, sudser and none of that has changed.

I can symlink apt cache and move off rootfs - who knows why it's not anyway, keep the default 4 enabled, add testing, tools and devels. and IIRC you'll see 4-5% additional usage - I can also move off some other things, but I really hate doing any of this because it can get very convoluted and prone to being forgotten about later.

Any other useful tips or why this growth with relatively little activity? I know, search and ye shall find, but biggest question is what the heck has taken another 5% over a week.

As many have mentioned, this tight space and the way Nokia has chosen to use rootfs rather than internal mmc for some of what is on rootfs (i.e. via symlinks) seems to be a constant battle. In the past I have done a bunch of symlinking and saw no problems related to it (other than having to keep track of what I've done and add one more thing to my 'worry' list/list of variables if an issue pops up.
