Hellenthal >Organization: >Confidential: no >Synopsis: Make 220.backup-pkgdb cd(1) and backup only the package database. >Severity: non-critical >Priority: medium >Category: conf >Class: change-request >Release: FreeBSD 8.2-STABLE i386 >Environment: System: FreeBSD 8.2-STABLE #0 r220564M Tue Apr 12 10:02:17 EDT 2011 i386 >Description: Currently the backup script archives a full path starting from '/' and then strips the leading slash off of the path which is correct. Upon extraction that full path without the leading slash is extracted in the current directory as var/db/pkg/<contents> with the first two and possibly more directories left empty. If a user has a different PKG_DBDIR as designated by ports(7) that is larger this can lead to frustration with the length of emptiness in the archive with the leading paths. >How-To-Repeat: Run ( /etc/periodic/daily/220.backup-pkgdb ) and extract the archive located in /var/backups/ >Fix: This patch makes 220.backup-pkgdb respectifully cd to where the pkgdb is located and create the archive from the relative path so there is only the pkgdb directory and contents upon extraction. http://patches.jhell.googlecode.com/hg/220.backup-pkgdb_cd.patch?r=f60df831e62d64fd336b6c6612a6619eaf17a17f diff -r aa37d382121b -r 3fbae1ba29a4 etc/periodic/daily/220.backup-pkgdb --- a/etc/periodic/daily/220.backup-pkgdb +++ b/etc/periodic/daily/220.backup-pkgdb @@ -33,7 +33,8 @@ new_bak_file=`mktemp ${bak_file}-XXXXX` - if tar -cjf "${new_bak_file}" "$pkg_dbdir"; then + cd $pkg_dbdir/.. + if tar -cjf "${new_bak_file}" "$(basename $pkg_dbdir)"; then chmod 644 "${new_bak_file}" if [ -e "${bak_file}.2" -a -e "${bak_file}" ]; then
