Thanks Ryan, what we see is: the only - really is none at all
localhost64 ffmpeg-0.4.9-p20060302-shared # du -csh /cvs/gentoo-x86/
768M /cvs/gentoo-x86/
768M total
localhost64 ffmpeg-0.4.9-p20060302-shared # du -csh /cvs/gentoo-x86/
- --apparent-size
224M /cvs/gentoo-x86/
224M total
i waste more on the wrong block size with /cvs/gentoo-x86/ being on my
4K block size partition than the file size would add
we could trick around to get all that smaller
but let's be real for a moment, let's double the 768M, 1536M is nothing
on today's machines, drive space is cheap, and if your disk is small,
then you have no business running cvs or svn or anything with lot's of
small files on 4k block size
so looking at the list of SCMs, svn has only plus, and a theoretical -
side that in 2006 is none
" --apparent-size print apparent sizes, rather than disk
usage; although the apparent size is usually smaller, it may be
larger due to holes in (`sparse') files, internal
fragmentation, indirect blocks, and the like"
so put svn on a partition with small blocksizes/inode sizes and let's
get on with the program
