RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
Currently no one tells where the mapped device created by luks-open is. It's completely the user's job to read the manual and take '/dev/mapper/mapname'. Guestfish should help to remember this name.

Version-Release number of selected component (if applicable):
libguestfs-1.7.17-15.el6

How reproducible:
always

Steps to Reproduce:
1.
...
><fs> luks-open /dev/sda1 map1
Enter key or passphrase ("key"): 
><fs> list-devices 
/dev/vda
><fs> list-filesystems 
><fs> mount /dev/[TAB]
/dev/vda   /dev/vda1  

  
Actual results:
We wanted to get the mapped device name from the tab completion, but failed.
We can't either see it from list-devices or list-filesystems.
However, `mount /dev/mapper/map1 / ` works fine.

Let's try to fix this for 6.2.  Should be very simple.

Patch posted upstream:

Reproduced in -1.7.17-19 and verified in -1.7.17-26.

$ guestfish

(-19 does not have the /dev/mapper/luks1 entry, -26 does.)
