At first i thought that wouldn't be a problem but then i unmounted the device once and tried to read on it (i made "ls") and my system freezed and then rebooted, as i had pushed the reset-button. While using mount the normal way, i'm not having any problems. >How-To-Repeat: at first the relevant entrys of my fstab: .. /dev/acd0 /cdrom cd9660 ro,noauto 0 0 /dev/acd1 /cdrom1 cd9660 ro,noauto 0 0 here the sequens of commands i used: #su #mount /cdrom #mount /cdrom #mount .. /dev/acd0 on /cdrom (cd9660, local, read-only) /dev/acd0 on /cdrom (cd9660, local, read-only) #umount /cdrom #mount .. /dev/acd0 on /cdrom (cd9660, local, read-only) #ls /cdrom --freeze and reboot-- (this also "worked" on a 6.2-PRERELEASE box) >Fix: >Release-Note: >Audit-Trail: >Unformatted:
