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:
1. For sgdisk, -t, --typecode=partnum:{hexcode|GUID}, it can accept hexcode as input
For guestfish, we'd better update the helpout of part-set-gpt-type according to sgdisk, tells that hexcode is valid, command does not return error.
2. If gives a non-guid format value, sgdisk will give a default guid, like:
# sgdisk /dev/sdb -t 1:f
Exact type match not found for type code 000F; assigning type code for
'Linux filesystem'
For part-set-gpt-type, if gives a non-guid format value for gpt, the default value is returned, it's equal to mbr's guid (0FC63DAF-8483-4772-8E79-3D69D8477DE4).
it does not match gpt, we also need update helpout for this
Version-Release number of selected component (if applicable):
libguestfs-1.22.6-8.el7.x86_64
How reproducible:
100%
Steps to Reproduce:
1. check for mbr
><fs> part-disk /dev/sda mbr
><fs> part-get-gpt-type /dev/sda 1
0FC63DAF-8483-4772-8E79-3D69D8477DE4
2. check for gpt
><fs> part-disk /dev/sda gpt
><fs> part-get-gpt-type /dev/sda 1
EBD0A0A2-B9E5-4433-87C0-68B6B72699C7
3. set an invalid guid for gpt
><fs> part-set-gpt-type /dev/sda 1 f
><fs> part-get-gpt-type /dev/sda 1
0FC63DAF-8483-4772-8E79-3D69D8477DE4

Verified with libguestfs-1.22.6-20.el7.x86_64
Check valid GUID value
><fs> part-get-gpt-type /dev/sda 1
EBD0A0A2-B9E5-4433-87C0-68B6B72699C7
Check invalid GUID value
><fs> part-set-gpt-type /dev/sda 1 f
libguestfs: error: part_set_gpt_type: guid: parameter is not a valid GUID
It gives a clear error message, so bug is fixed.
