New Partition for /home

Yet another time, I make a small sized partition for /home. And so, I took some time to go through helps and create a new partition. 1. Made a new partition by resizing an existing drive using gparted. 2. copied everything from /home using rsync --> sudo rsync -axS --exclude='/*/.gvfs' /home/. /mnt/newhome/. 3. Added the new drive as /home in /etc/fstab and removed the listing for the old /home folder from fstab file and rebooted. Here is my source link : http://www.hackourlife.com/move-home-to-a-new-partition-ubuntu-10-04/

managing shared libraries

Libraries have been installed in:
/usr/local/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
