Subject: [gentoo-user] Disk usage during emerge

1 Hello list
3 It came to my attention that during (after) an emerge run, df reports
4 considerably less space available on my / than before the emerge (everything
5 except /home sits on the root partition). I was wondering how this comes to
6 be, since I have /var/tmp/portage on tmpfs.
8 I am in the middle of a KDE upgrade (4.8.0→4.8.1) right now and before I
9 started, I downloaded all distfiles and then looked at df /, it showed 1022
10 blocks, hence about 1 GB of free disk space. I am at package 115 out of 174
11 right now, and df shows a mere 389k blocks remaining.
13 Also before I began the emerge run, I started 'ncdu -x /' which scans all dirs
14 on the / partition and then I can browse through my FS hieararchy, showing the
15 disk usage of every directory. Now I ran the same ncdu command again in
16 another screen, so I can compare it with the first one.
18 The folders themselves have 0.1 to 0.2 GB difference between their old and new
19 state, and ncdu's bottom bar even shows the same values for both apparent and
20 real total disk usage (rounded to 0.1 GB). So what am I missing here? I
21 searched df's man page for something about apparent sizes/sparse files, but
22 then again, why would portage create such files in the first place?
24 Do you have any thoughts that might help me understand what I'm seeing?
