Ultimately that's because Debian's the only place where the older "btyacc" is packaged. > * The packages are tiny (about 100k) and have no conflicting files. > /usr/bin/byacc2 and /usr/bin/byacc could be shipped in on binary > package. yes, I could do that. I don't believe that would interfere with using the alternatives mechanism for selecting "yacc". I made them separate because I thought that would be the expected way. > * Is the double compilation/binary necessary? - Is /usr/bin/byacc2 I thought it would be the safest approach. I've made some effort to keep the two compatible, but sooner or later will get some bug report related to their differences. Debian's the usual place for that sort of thing. > incompatible with /usr/bin/byacc2?

(I should make a list of the other packages, but the rpm's are easy to check at the moment). -- Thomas E.
