on rc.sysinit there is a posible "race condition" between calling getkey (for interactive startup) and killing getkey (before starting selected runlevel scripts) { # Clean up utmp/wtmp >/var/run/utmp touch /var/log/wtmp chgrp utmp /var/run/utmp /var/log/wtmp ... kill -TERM `/sbin/pidof getkey` >/dev/null 2>&1 }& if [ "$PROMPT" != "no" ]; then /sbin/getkey i && touch /var/run/confirm fi wait as you can see, if the code between the {} runs too fast, you could end with an stalled "getkey" waiting forever for input (as i have experienced on some Compaq Dual Processor, Hardware RAID systems and the simpler script from RH6.2) to be fair, i've been unable to reproduce the same "hung" on 7.0final but there is a theorical posibility that if given enough resources this could happen (there seems to be a need for about 1 second before the kill is reached for getting a successfull kill of getkey) my solution was to patch rc.sysinit so getkey is called with a "timeout" parameter (seems like someone on RH tought it could happen before and added the timeout parameter but no fix on the rc.sysinit script) if [ "$PROMPT" != "no" ]; then /sbin/getkey -3 i && touch /var/run/confirm fi wait RH6.2's getkey doesn't have the "timeout" parameter so a backport should be released with the modified rc.sysinit to fix this problem.
solved for RH 6.2, could be used on 7.0 and others *** This bug has been marked as a duplicate of 17842 ***
