So... there is a notebook far away from me, and I can only sit in front of it in about a month. So I'm searching for a solution - "remotely".
Scientific Linux 6.3 is installed on it, and it worked perfectly. One day the people that use it sent me this picture.
Q: How can I fix the GRUB menu? So that they can use the notebook again?
P.S.: There was an auto-update configured on that machine besides the base install, here is how I implemented it:
yum remove -y PackageKit* yum-autoupdate yum-updateonboot; read; vi /etc/yum-update
cat yum-update
#!/bin/bash
# run an update in at least every 172800 seconds [in at least every 48h]
# wait for random time: 0-2700 sec [0-45min]
/bin/sleep $[ ($RANDOM % 2701 ) ]
if [ `stat --format=%Y $0` -le $(( `date +%s` - 172800 )) ]; then
# sync time - http://www.pool.ntp.org/zone/hu
/usr/sbin/ntpdate time.kfki.hu 0.hu.pool.ntp.org; /sbin/hwclock --systohc
# do updates
/usr/bin/yum -q -y update
/usr/bin/yum clean all
# update last modification time + create log entry
/bin/touch $0
/bin/echo "/etc/yum-update OK" | /usr/bin/logger
fi
chmod +x /etc/yum-update; crontab -e
52 * * * * bash /etc/yum-update
P.P.S.: They tried to press up/down when the machine booted (hoping to select another kernel) but it didn't help.
