[Libguestfs] virt-sysprep cron-spool, no at jobs

sysprep/sysprep_operation_cron_spool.ml claims to remove at jobs, but those are not stored in /var/spool/cron/ on my system. Is the description wrong, or do other distros store the spool data in the cron dir? For me it looks like this (000110156d537 is currently executed): root@probook:~ # find /var/spool/at* -ls 67540 1 drwx------ 2 at at 1024 Sep 19 18:55 /var/spool/atjobs 68080 6 -rwx------ 1 olaf users 5203 Sep 19 18:54 /var/spool/atjobs/=000110156d537 67539 1 -rw------- 1 at at 6 Sep 19 18:54 /var/spool/atjobs/.SEQ 67984 6 -rwx------ 1 olaf users 5257 Sep 19 18:52 /var/spool/atjobs/a000100156d678 67542 1 drwx------ 2 at at 1024 Sep 19 18:55 /var/spool/atspool 68169 1 -rw------- 1 at at 49 Sep 19 18:55 /var/spool/atspool/a000110156d537 Olaf
