[pkg-bacula-devel] Bug#714161: bacula-director-mysql: run AfterJob "/etc/bacula/scripts/delete_catalog_backup": ERR=Permission denied

Package: bacula-director-mysql
Version: 5.2.6+dfsg-9
Severity: normal

Hi there,

on a fresh Bacula Director installation I get the following error at the
end of the BackupCatalog default job:

  JobId N: shell command: run AfterJob "/etc/bacula/scripts/delete_catalog_backup"
  JobId N: Error: Runscript: AfterJob returned non-zero status=200. ERR=Permission denied

The reason is quite clear, despite the permissions being correct in the
"source" file:
=====
# ls -l /etc/bacula/scripts/delete_catalog_backup 
-rw------- 1 root root 104 Jun 26 14:07 /etc/bacula/scripts/delete_catalog_backup
# ls -l /usr/share/bacula-common/defconfig/scripts/delete_catalog_backup 
-rwxr-xr-x 1 root root 112 Apr 23 22:05 /usr/share/bacula-common/defconfig/scripts/delete_catalog_backup
# 
=====

The problem is in /var/lib/dpkg/info/bacula-director-mysql.postinst:72
and /usr/share/bacula-common/common-functions.dpkg:95:

--8<---------------cut here---------------start------------->8---
     70   DBNAME="$dbc_dbname"
     71   SUBST_VARIABLES=DBNAME
     72   install_config \
     73     bacula-director-mysql \
     74     /usr/share/bacula-common/defconfig/scripts/delete_catalog_backup \
     75     /etc/bacula/scripts/delete_catalog_backup
--8<---------------cut here---------------end--------------->8---

Given how we treat such files (not really conffiles, but still), IMHO
the easiest solution is to manually set the permissions in .postinst:

--8<---------------cut here---------------start------------->8---
