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 Ben Breard 2022-03-01 02:30:30 UTC 
Description of problem:

When installing a RHEL for Edge system using the simplified installer, the boot time is very long. A system that should take ~10-15 seconds to boot, will take about 2 minutes. What ever is going wrong happens incredibly early in the boot process. When this is happening, the UEFI splash screen will stay for a *long* time. I've tried power cycling, disabling the fdo unit - nothing seems to help. 

This issue may belong to the coreos-installer. 

Version-Release number of selected component (if applicable):
RHEL 9 nightlies 
fdo-client-0.3.0-1.el9

How reproducible:
100%

Steps to Reproduce:
1. create an edge image using the simplified-installer type
2. install to disk
3. watch the boot time

Actual results:
The system will take a relatively long time to boot. Also, systemd-analyze blame will report jobs are still running.

Expected results:
Boot speeds should not be negatively impacted with using the simplified installer and FDO

the fact that disabling the fdo-client unit does nothing makes me think this isn't the issue
maybe we should take a look at the package/service set we ship but I'm positive they are the same as we ship with the Anaconda installer
have you tested both anaconda and simpl installer?

Comment 2 Antonio Murdaca 2022-03-01 08:31:45 UTC 
also, afaict, the slow down is on "real" devices (like my fitlet2) - on virtual machine this doesn't happen (they boot just as fast as you'd expect)
Comment 3 Antonio Murdaca 2022-03-01 08:52:48 UTC 
ok, I think I've found the difference between simplified installer and anaconda and it boils down to https://bugzilla.redhat.com/show_bug.cgi?id=1839923 - so w/o reading up that bz, we're adding console= kargs in the system image with simplified installer where anaconda doesn't and leave console to the kernel - I'm creating a patch for that after testing it out
Comment 4 Antonio Murdaca 2022-03-01 08:56:18 UTC 
Ben, the workaround is:

sudo rpm-ostree kargs --delete "console=tty0"
sudo rpm-ostree kargs --delete "console=ttyS0"

The system will boot just as normal speed afterwards
