[Bug 465690] New: root is not able to login when filesystem is r/o
https://bugzilla.novell.com/show_bug.cgi?id=465690 Summary: root is not able to login when filesystem is r/o Classification: openSUSE Product: openSUSE 11.1 Version: Final Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem AssignedTo: mc@novell.com ReportedBy: meissner@novell.com QAContact: qa@suse.de CC: security-team@suse.de Found By: Development my harddisk (one partition / , one /home) somehow remount / as readonly. I was no longer able to login as user (ok), and no longer ablke to login as root (bad). The error message seemed to come from the PAM stack somewhere. "Fehler im Service-Modul" is the errormessage I think it should still be possible to login as root, even with / read-only. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

(starting hal-deamon waits forever) In runlevel 1 I was able to login as root even with ro mounted / . A reason for the message "Error in Service Module" could be session required pam_lastlog.so If pam_lastlog cannot write, it returns exactly this error. Thorsten do not want to create an exception for root there, because other customer will require that every login must be logged and there security policies will reject such a behaviour. And even if we would implement such an exception it is not clear if other programms requires write access, e.g. login to wtemp and maybe also bash. In general this "somehow remount / as readonly" is a bug elsewhere. This should be fixed. Thorsten and I decided => wontfix. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
