>Description:
First, please note the above Release and Environment statements are not
from a RELENG_7 box (obviously :-) ). The issue I'm describing is
specific to RELENG_7's version of tar, which differs from RELENG_8.
RELENG_7 tar spits out a warning when attempting to tar something
with a leading slash:
Backing up package db directory:
tar: Removing leading '/' from member names
RELENG_8 tar has different logic in util.c, causing it not to output
said warning. I'm not sure if there's any effort underway to backport
RELENG_8's tar to RELENG_7.
>How-To-Repeat:
Run /etc/periodic/daily/220.backup-pkgdb on a present-day RELENG_7 box.
>Fix:
There's multiple ways to fix this, but I think the easiest is to
simply redirect stderr to /dev/null like so (diff):
- if tar -cjf "${new_bak_file}" "$pkg_dbdir"; then
+ if tar -cjf "${new_bak_file}" "$pkg_dbdir" 2>/dev/null; then
I've tested this on a RELENG_7 (7.4-STABLE) box dated 2011/04/30 and
it does work.
