ouch. you have my sympathy. thanks for testing, I hope you did so |
| 13 |
with careful planning? :-) |

good point. I thought that should be easy enough to check so I |
| 20 |
created a small logical volume directory for testing. I then ran |
| 21 |
prelink -v /mnt/prelink/*.so, and even if the partition was 100% |
| 22 |
full it ran okay. well, seemingly at least. nothing ended up as |
| 23 |
"data". I wonder what libraries cause massive space usage? |

I noticed the space on /usr having 50MiB free at one point, and |
| 30 |
dropping down to around 10MiB when I reran "prelink -u". I'd say |
| 31 |
that 100MiB should be plenty, and probably give us a bit of |
| 32 |
headspace as well. I'll try to reproduce the events under |
| 33 |
controlled circumstances. |
| 34 |
|
| 35 |
anyhow, since /etc/prelink.conf contains all the stuff that can be |
| 36 |
broken, this find everything that is broken, and then some: |
| 37 |
|
| 38 |
for build in $( |
| 39 |
for broken in $( |
| 40 |
for dir in $( grep -v '#' /etc/prelink.conf | cut -f2 -d' ' ); |
| 41 |
do |
| 42 |
file $dir/* | grep ":.*data"; |
| 43 |
done | cut -f1 -d: ); |
| 44 |
do |
| 45 |
qpkg -v -nc -f $broken; |
| 46 |
done | sort | uniq ); |
| 47 |
do echo "=$build"; done |
| 48 |
|
| 49 |
produces a nice list to feed emerge: |
| 50 |
|
| 51 |
=dev-util/guile-1.4-r3 |
| 52 |
=gnome-base/gnome-panel-1.4.1 |
| 53 |
=kde-base/kdebase-3.0.5a |
| 54 |
=kde-base/kdelibs-3.0.5a |
| 55 |
=kde-base/kdemultimedia-3.0.5a |
| 56 |
=media-video/transcode-0.6.0 |
| 57 |
=media-video/xawtv-3.80 |
| 58 |
=net-print/cups-1.1.18 |
| 59 |
=sys-libs/cracklib-2.7-r6 |
| 60 |
=sys-libs/db-1.85-r1 |
| 61 |
=x11-libs/qt-3.1.0-r1 |
| 62 |
|
| 63 |
emerge $( for ... ) works as it should, and grabs the proper |
| 64 |
versions. |
| 65 |
|
| 66 |
the only false positive I find comes from /usr/lib/cracklib_dict.hwm |
| 67 |
and will require a remerge of cracklib, which isn't that bad. one |
| 68 |
can of course just grep that away, if you know it's clean. there is |
| 69 |
also the issue that ORBit2 required me to delete the broken |
| 70 |
libraries by hand, and also that packages have to be built in the |
| 71 |
correct order. building kdelibs with a broken kdebase doesn't quite |
| 72 |
work. but, at least the above script should ease ones pain. |
