I know the general format for package names in Debian and Ubuntu. Some packages have additions to the standard numbering scheme with obvious meaning like svn20090426
etc. But also quite a few packages have dsfg in their name (e.g. 2:1.0~rc4~try1.dsfg1-1ubuntu1
) – what does that mean?
Is it just a typo of the Debian Free Software Guidelines (DFSG)?
http://en.wikipedia.org/wiki/Debian_Free_Software_Guidelines
A package with 'dfsg'/'dsfg' suffix is one that has been stripped of any files that doesn't follow the Debian Free Software Guidelines.
(From Debian mailing list: http://lists.debian.org/debian-mentors/2010/08/msg00169.html)
I don't think dsfg is a "typo" I think it's more of a ACRONYM for Debian Free Software Guidelines (DFSG). Just my two cents.
