Background: I'm really a Fedora person: I've been running RedHat distros 
since RH 6.2 and Fedora from 1 to 22, though with a few skipped along the 
way. Both my bigger boxes use Fedora and in consequence I find using apt-
get less straight-forward than yum (and now dnf since F21).

Initially I was just using update, upgrade in that order. Then I decided 
that dist-upgrade would be useful, and read the manpage which doens't 
give a preferred order (why not fer chrissakes?) but seemed to be hinting 
that that it should preceed update, so that's where it is run.

About a year back I discovered autoclean and put it first on the grounds 
that its nice to clean house before getting in more stuff. In fact I 
don't think it matters whether its first or last because, with the 
sequence being run about once a week, it is always run after the last 
upgrade in the cycle. I think the same argument applies to dist-upgrade.
BTW, one of my first action was to disable auto-update because I like to 
do a backup before an update/upgrade sequence. Similarly, I've used the 
same manual backup+update sequence for years on the Fedora boxes.

Yes, I thought so. This RPi was one of the first batch of 512MB B models 
and its been updated roughly weekly since then. Cruft has accumulated, 
even with the last year's inclusion of autoclean in the upodate cycle. It 
had steadily grown: when first installed df showed about 2.2 GB of stuff 
on the SD card and, up to last week that had steadily grown to 3.2 GB. 
Somewhere along the line my original 4GB card got replaced with an 8GB 
one. Anyway, I noticed that after jessie had been installed the card had 
about 3.5 3.6 GB of stuff on it and that running my update sequence 
reported a lot of package deletions, so was pleasantly surprised to see 
that post autoclean df is reporting that 2.8GB of the card is used.

Thanks for that.

Yes, manual Fedora shutdowns usually take the form "sudo shutdown -h NOW" 
but I normally (lazily) shut down with the button on the login screen and 
I haven't tried to find out what command it uses for reboot or halt.

I've always just assumed that reboot, halt and poweroff were just 
convenience wrappers for shutdown. If fact I'd never run across them 
until I got the RPi: all the Unices I've used and early Redhat Linux 
tended to assume that you would just user shutdown.
