Do not reserve filesystem blocks on /home and possibly other partitions
Last modified: 2007-11-30 17:11:24 EST
By default ext2 and ext3 filesystems reserve %5. While this is useful for /,
/tmp, and /var, this wastes precious harddisk space for /home, and since /home
is probably the biggest partition users create, not reserving %5 on /home, or
reserving %1 returns something like 2GB of harddisk space that is unusable
The reservation isn't there solely for the purposes of not filling up the disk.
ext also needs that reserved space to avoid particularly bad fragmentation.
Why must your preference be the default? I'm it has a useful purpose.
