This laptop runs KDE, here's my breakdown: # du -sh /usr 13G /usr # du -sh /usr/* 12K /usr/INSTALL 104K /usr/Licenses_for_Third-Party_Components.txt 426M /usr/bin 12M /usr/gnu-classpath-0.98 460M /usr/include 0 /usr/lib 525M /usr/lib32 2.8G /usr/lib64 134M /usr/libexec 512K /usr/local 38M /usr/sbin 3.6G /usr/share 4.9G /usr/src 0 /usr/tmp 11M /usr/x86_64-pc-linux-gnu Those numbers are not likely to change much with time, with one exception: /usr/src That can get real big real quick if you don't clean up kernel sources often. Ideally, you'd make that a suitably sized LV and mount it seperately. The other space consumer is /usr/share with it's many documentation files. But those too tend to be stable once you have everything installed. 5G free out of 19G is ~75% space in use which is perfectly acceptable for this case. Regular monitoring of the state of your machines will tell you if space usage increases so you can investigate and deal with it timeously. I assume you long since moved portage and it's storage directories out of /usr into /var? -- Alan McKinnon alan.mckinnon@gmail.com
