Hello all, I am struggling here with the most weird thing to date (for me). These are the facts: I cannot log into my FC5 box. While booting I get lots of error messages: "unknown user: root"; starting rescue mode from CD and chrooting the old system behaves strangely: - I start mc and I try to modiy any text file - when i press a key it will crash instantly. - whoamy responds "cannot find name for user ID 0" - passwd responds "Can not identify you!" My checks: - I verified the file system - seems OK; - I compared shadow with shadow- = 7 bytes difference - I compared groups with groups- = OK - I compared passwd with passwd- = OK All this started after rebooting the system ; I was just finished the update process - installed kernel kernel-2.6.16-1.2111_FC5, installed the latest updates as of 2006-05-09 10:45 AM. Can someone explain to me what could be wrong with this system? I would prefer to repair the system instead of completely reinstall it (lots of settings to remember). Thank you in advance! marian
