.sys-Handler trying to use `debconf-get-selections` on CentOS 7
I'm on CentOS 7, and I've got a job running that does daily backups of the system configuration using the .sys-Handler. Unfortunately, I get the following warning each time:
Warning: can't find debconf-get-selections, skipping package selection states. You might want to install the debconf-utils package.
CentOS Linux release 7.3.1611 (Core) and
backupninja 1.0.1-8.el7 from EPEL.
The concerned lines are lines 238-240 in sys.in, if I'm not mistaken. It seems that the code handling vservers assumes that those vservers are running Debian. And it looks like setting
vservers = no in the central config doesn't prevent it from going through the vservers loop, because this is the only place where this warning can be thrown.
Do you have any contribution guidelines that I could look at before I go and try to contribute a patch for this? :)
Here's my config …
$ sudo cat /etc/backup.d/10-sysinfo.sys when = daily packages = yes partitions = no dosfdisk = no hardware = no luksheaders = no lvm = yes packagesfile = /var/backups/packages.txt # selectionsfile = /var/backups/debconfsel.txt # partitionsfile = /var/backups/partitions.__star__.txt # hardwarefile = /var/backups/hardware.txt # luksheadersfile = /var/backups/luksheader.__star__.bin # If vservers = yes in /etc/backupninja.conf then the following variables can # be used: # vsnames = all | <vserver1> <vserver2> ... (default = all)
loglevel = 3 reportemail = email@example.com reportsuccess = yes reportinfo = yes reportwarning = yes reportspace = yes reportdirectory = /var/lib/backupninja/reports admingroup = root logfile = /var/log/backupninja.log configdirectory = /etc/backup.d scriptdirectory = /usr/share/backupninja libdirectory = /usr/libexec/backupninja usecolors = yes when = everyday at 03:42 vservers = no
… as well as the output when I do a test run of the action using
