getdirs.awk: - improve parsing; explicitly skip lines we don't want and use the rest. - keep track of which items were explicitly listed, and only output directories at the END which weren't listed, each with a suffix of "optional". - convert to my awk KNF join.awk: - when joining, output all of the matching entry from the first file and the 2nd & subsequent lines of the entry from the second file. - convert to my awk KNF these changes mean that maketars use of pax will result in tar files with the traditional behaviour of only containing the necessary directories, rather than all the parent directories required to get to a particular item. this latter behaviour was necessary for METALOG (i.e UNPRIVED) pax .tgz set file generation, until the changes above fixed it.

# $NetBSD: getdirs.awk,v 1.2 2002/05/19 13:32:44 lukem Exp $
Fixes to allow unprivileged building of the binary tar files to contain the correct permissions. Makefile: - set SETSENV to the list of variables we wish to pass to each shell script and use that, rather than duplicating the effort below - call maketars with "-M ${METALOG}" if UNPRIVED is set. getdirs.awk: - takes a list of filenames and outputs the list along with all the directories used by those filenames maketars: - support "-M metalog" - merge etc/mtree/NetBSD.dist with the "-M metalog" for use in the tgz build - for a given set, find the union between the set list and the metalog generated above and use that as the list of files to ${PAX} up as the tgz file.

Fixes to allow unprivileged building of the binary tar files to contain the correct permissions. Makefile: - set SETSENV to the list of variables we wish to pass to each shell script and use that, rather than duplicating the effort below - call maketars with "-M ${METALOG}" if UNPRIVED is set. getdirs.awk: - takes a list of filenames and outputs the list along with all the directories used by those filenames maketars: - support "-M metalog" - merge etc/mtree/NetBSD.dist with the "-M metalog" for use in the tgz build - for a given set, find the union between the set list and the metalog generated above and use that as the list of files to ${PAX} up as the tgz file.
