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 Paulo Andrade 2020-10-02 17:24:49 UTC
This issue is similar to previously reported issue at
https://bugzilla.redhat.com/show_bug.cgi?id=1520906
[make hostname in login(1) prompt optional]

The problem is that to be complete, it would also require
agetty to also understand /etc/login.defs LOGIN_PLAIN_PROMPT
value. Otherwise, it would be required some wrapper passing
--nohostname
The patch would not be so trivial, as would most likely require
a copy of login-utils/logindefs.c added to term-utils and make
agetty use it. Once added, the pseudo patch would be:

term-utils/agetty.c:
"""
 				printf(_("Hint: %s\n\n"), hint);
 		}
 	}
 #endif /* KDGKBLED */
+	if (!(op->flags & F_NOHSTNAME) &&
+ 	    (getlogindefs_bool("LOGIN_PLAIN_PROMPT", 0) == 1)
+		op->flags |= F_NOHSTNAME;
 	if ((op->flags & F_NOHOSTNAME) == 0) {
 		char *hn = xgethostname();
"""

Comment 7 Karel Zak 2022-03-18 09:55:52 UTC
Note that --nohostname is already usable for this purpose, all you need is to configure the service that systemd uses to call agetty. But yes, /etc/login.defs LOGIN_PLAIN_PROMPT sounds more elegant for end-users.

Comment 8 Karel Zak 2022-03-30 09:20:49 UTC
Implemented in upstream tree: https://github.com/util-linux/util-linux/commit/556925fe4e63719756ce32c904e887d89d81f5b9

... but  I don't think this is something we can (and want) backport to RHEL-7 or RHEL-8, maybe we can try it later for RHEL-9.1 or so.
