The options would seem to be: > 1) Stick with gzip for 7-src and earlier (as well as ports until 7.x > goes EOL) (Not that I'm suggesting for or against Option 1, but it needs modifying, Applying the same logic, append to Option 1: "as well as cvs-cur" (as cvs can be used to extract eg 4 & ports & doc as well as head). As the ctm collection comprises: cvs-cur ports-cur src-4 src-5 src-6 src-7 src-8 src-cur Option 1 thus becomes "Stick with gzip for all except src-8 & src-cur" Whether a CTM src-stable stream is EOL is irrelevant. All that matters is whether extractor hosts have xz or not. One does not need to run ctm on same `uname -r` as one extracts for, eg my CTM extractor runs on 8.3, but I extract for all of cvs-cur ports-cur src-4 src-5 src-6 src-7 src-8 src-cur Some (4, maybe 6) have long been EOL, but I use them for reasons beyond remit of this thread. > 2) Make ctm a port (so it can have a dependency on xz) I cant imagine many CTM users saying "please kick CTM out of src/" ;-) > 3) If dispensation is granted, Dispensation for what ? > ensure the dependency is documented in > UPDATING and ctm.1 when it is MFC'd to 7.x and before. Man ctm says: "The ctm command appeared in FreeBSD 2.1" In theory someone could be extracting on a really old host ? We might be lucky & find all people are extracting on 8.x ? We won't know unless we ask, Stephen could request on ctm-announce@ eg: "People extracting CTM on old systems are requested to run uname -r & if not 8.something-RELEASE or current, report to ....@.... Personaly, I'd think an acceptable middle course could be to switch to whatever reduces the CTM bandwidth the most & put a note in man ctm: "If running FreeBSD-x or earlier you need to cd /usr/ports/archivers/xz ; make install" Cheers, Julian -- Julian Stacey, BSD Unix Linux C Sys Eng Consultants Munich http://berklix.com Reply below, not above; Indent with "> "; Cumulative like a play script.
