A friend on the phone helped me alot : in console mode, he hinted that I removed a huge package. Openoffice.org removed, I had 175 free megabytes again, and I could finally manage to boot my Mandriva properly. Phiew, i'm relieved.
But I still have ONLY 175 free megabytes on /
Whereas the previous graphical-mode session, I had 950 Mo free.
One of the possible causes of that problem is that a package update completely froze and had to be forcibly closed after ten minutes of inactivity. And the NFS thingie, at system startup, didn't close either after ten minutes waiting during shutdown, hence making me manually shutdown the computer. Next reboot, partmon said there was 0 byte free in /.
I'm somehow confused, you'll guess that ^^
Would you know where the missing megabytes could have gotten lost ?
And how to free space on / ?
I guess there MUST be a way to make space within the /var/log folder : even if some files are necessary, I can't trust a linux system, even Mandriva2006, to require one gigabyte of logs.
Help will be welcome if you can ^_^
