I have a small question about the difference in contents
between the "live" DVD and "inst" CD versions of TeX Live 2005.
Looking at http://www.tug.org/texlive/, I understand there
are 2 differences between the 2:
[PACK] The TeX Live 2005 "live" DVD contains unpacked files,
while files on the CD are compressed,
[XTRA] The "live" DVD contains extra stuff (proTeXt, MacTeX
and a snapshot of CTAN).
I expect the extra material in [XTRA] adds up to a substantial
amount of data.
Now, looking at http://www.tug.org/ftp/texlive/Images/ I notice:
texlive2005-inst-20051102.iso 02-Nov-2005 01:33 682M
texlive2005-live-20051102.iso 02-Nov-2005 01:11 1293M
DVD image size = 2 x the CD; fine, uncompressed and extra material.
texlive2005-inst-20051102.iso.bz2 27-Nov-2005 02:22 653M
texlive2005-live-20051102.iso.bz2 27-Nov-2005 02:37 587M
After compression, the DVD image becomes smaller than the CD!
I believe that compressing the image gives better results than
compressing each file individually, maybe BZ2 offers better
compression than TAR.GZ/ZIP, but where does the (lots of) [XTRA]
stuff go? And if after compressing everything, it fits in less
than 650M, why would be anything left off the CD?
So my question: is there any difference between the 2
in what files/ directories are included, or it's just the
Thanks in advance for any clarification,
