Fixed In Version:	libguestfs-1.20.11-16.el6	Doc Type:	Release Note
Doc Text:	The "at" program works correctly with "virt-sysprep" When using the "virt-sysprep" utility to create a Red Hat Enterprise Linux guest template, the "at" program in the resulting guest could not be used. This update ensures that "virt-sysprep" does not delete `/var/spool/at/.SEQ` files in these guests, and "at" now works as expected.	Story Points:	---

Description Martin Schuppert 2015-06-08 12:30:51 UTC

Description of problem:

virt-sysprep's cron-spool operations removes /var/spool/at/.SEQ . .SEQ contains at job counter (5 digit hex)
/var/spool/at]$ cat .SEQ 
00001

# virt-sysprep --list-operations
..
cron-spool * Remove user at-jobs and cron-jobs

Removing this file results in that at can not be used afterwards without manual create of this file:

[root@localhost /var/spool/at]$ at now + 1 minute
Cannot open lockfile /var/spool/at/.SEQ: No such file or directory

.SEQ file needs to be recreated to fix this. We should reset the counter manually by changing the /var/spool/at/.SEQ file to 00000, or recreate after deleted by virt-sysprep.

Version-Release number of selected component (if applicable):
* libguestfs-tools-c-1.20.11-11.el6.x86_64
* # virt-sysprep -V
virt-sysprep 1.20.11

How reproducible:
always

Steps to Reproduce:
1. [root@localhost /var/spool/at]$ rm -f .SEQ 
2. [root@localhost /var/spool/at]$ at now + 1 minute
Cannot open lockfile /var/spool/at/.SEQ: No such file or directory

Actual results:
[root@localhost /var/spool/at]$ at now + 1 minute
Cannot open lockfile /var/spool/at/.SEQ: No such file or directory

Expected results:
at works without manual action after virt-sysprep

Comment 5 Xianghua Chen 2015-12-07 02:54:57 UTC

Verified with the packages:
libguestfs-1.20.11-16.el6.x86_64
libguestfs-tools-c-1.20.11-16.el6.x86_64
# virt-sysprep -V
virt-sysprep 1.20.11


Verify steps:
1. # cd  /var/spool/at/

2.# cat .SEQ
00001

3. # virt-sysprep --list-operations
abrt-data * Remove the crash data generated by ABRT
bash-history * Remove the bash history in the guest
blkid-tab * Remove blkid tab in the guest
......

4. # at now +1 minute
at>

No error occurs.


So verified.
