You can't simply add 4 to 2 because 3 is in the way (unless you're using LVM
or somesuch, and I guess you would have said if you were). So, you need to
delete 2,3 and 4, make a new bigger 2, make a 3 for swap, and use resize2fs.
Steps as follows (comments preced by # as usual - all others command to be
carried out as root)
# back up the data on /home
# back up the data on /home to a different physical medium
# no command given here, because there are so many different ways of
# doing this.
# put the system in single user mode
# stop using sda3 for swap
# unmount the filesystem on /dev/sda2
# now you must delete partitions 2,3 and 4, make a new bigger 2 (for /home)
# and make a new partition 3 (for swap). The new 2 MUST begin at the same
# sector as the old one, which will be the default if you follow the above
# resize the ext2 filesystem on partition 2 to be the size of partition 2
# with progress bars for that warm fuzzy feeling
resize2fs -p /dev/sda2
# create swapspace on partition 3
# mount the new enlarged /home filesystem
mount /dev/sda2 /home
# and check your data integrity in whichever way suits you e.g. by comparison
# of checksums with the backup copy.
If the above results in anything breaking, you get to keep ALL the pieces.
And most important of all - the above assumes that you're using ext2 on /home.
If you're not, the above won't work so don't do it. I'm sure there are
resizing programs available for other filesystem types but I haven't used
