du -hT doesn't work because --T is an invalid option. du -h gives
I have just mounted /home on a separate partition (20GB in size, so that should be plenty I'd say), with the help of http://www.swerdna.net.au/linhowtomovehome.html
. (I made some mistakes, so I was glad to have a dual boot, so I could undo my misdoings). After that I ran du -h again, but the result is the same, except for 5 entries (.../RecentDocuments, .../apps, .KDE/share, .KDE and . ), wich are a few kB bigger.
Could mounting /usr elsewhere (on the same alternative partition?) solve the problem? Not that I have a clue why, though.
Overusing space is not really an issue, considering that I have over 1 TB of hd space.
Btw, I suddenly had the problem that neither Google nor Yahoo worked (opening websites worked, just not the search), but that was gone after a reboot. Weird, and I'm not sure if it is in any way related to the problem at hand.
I have just done the same with /usr that I did with /home (except all as root this time), copying the contents to another partition, renaming the old /usr (to /usr_old) and creating a symbolic link from /usr to the new location. And the system started, so, impatient as I am, I deleted the contents of /usr_old (except that /usr/include wouldn't go). Konqueror said it was removing over 5 GB, but now I've still only got 3.7 GB free disk space. I still don't get how things don't add up like that. However, if that won't decrease anymore now that /home and /usr are elsewhere (is that a correct assumption?) then I've got nothing to worry about. Right? (Fingers crossed for the next reboot.)
