[opensuse] How to tell the kernel to _not_ find any SATA hard disks?
Hi there, I need $SUBJECT for the following situation: Skype should be used as a from-time-to-time conversation vehicle, but as I'm paranoid, I'm not going to install the binary-only blob onto my real system. Instead I'm trying to build an appliance which boots off a USB stick and which will _not_ find (and potentially auto-mount) any existing partitions/filesystems on the real (hard) disk(s). I've tried to use "brokenmodules=libata" (incl. any combination of additional "sd_mod" and/or "scsi_mod"), but failed as the system won't boot anymore. I thought this should be doable with some kernel parameters at GRUB time, but I haven't been able to do so (yet). Does anybody know how this can be done? TIA, cheers. l8er manfred -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I don't know whether this is in any style guide or whether it's just me but it irritates me when people write something like that, or when they say "I need the above" or when they just assume that the message text somehow flows on from the subject. To my mind, the author should do any cut-and-pasting required to make the message text self-contained and meaningful, not expect the readers to do it, even with explicit instructions like this. Sorry, I don't know the best way to do what you want :( Cheers, Dave -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

What about running skype in a virtual machine. -- Regards, Rajko -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

As I wrote (not in $SUBJECT, but in the message's body ;-), I want to store it on a USB stick so that I can carry it with me and boot from it on a random laptop without risking that any data on that system can be accessed.

Just to summarize what I found to work (in case anybody else needs this, too): - Using "brokenmodules=libata" at the Grub prompt doesn't work, as the system hangs afterwards. - Listing all modules in /lib/modules/`uname -r`/kernel/drivers/ata/ in /etc/modprobe.d/blacklist and then regenerating the initrd will cause the system to not find any SATA disk anymore after the next boot: # ls /lib/modules/*/kernel/drivers/ata/*.ko | \ sed -e 's,^/.*/\([^/]*\.ko\)$,blacklist \1,' | \ sort -u >> /etc/modprobe.d/blacklist In case a kernel update should be installed afterwards, you have to regenerate /boot/grub/device.map *before* installing the new kernel; something like # rm /boot/grub/device.map # echo "quit" | grub --batch generates a new one with (hd0) correctly referring to the USB stick. HTH, cheers. l8er manfred -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
