Disable HDD Detection ?

[mbzadegan]

Hi,
Is any way to disable HDD Drive detection while booting tinycore ?
I want to detect only my TinyCore USB Flash memory when i boot tiny core and don't want to detect MY HDD drives .

bootcode for this is nofstab

[mbzadegan]

i tested nofstab on booting kernel append line but nothing changed !
with ( or without ) nofstab , I could access to my HDD while i booting from USB Flash Memory.

Could be because of these udev rules. I would say this makes it a bug.
Perhaps rebuildfstab should also check if NOFSTAB is set.

/etc/udev/rules.d/98-tc.rules:ACTION=="add",      SUBSYSTEM=="block",   RUN+="/bin/sh -c '/usr/sbin/rebuildfstab'"
/etc/udev/rules.d/98-tc.rules:ACTION=="remove",   SUBSYSTEM=="block",   RUN+="/bin/sh -c '/usr/sbin/rebuildfstab'"

No such thing. Even if nofstab skips the convenience filters, you can still access the device yourself.

Hi mbzadegan
Maybe if you explain why you are trying to do this, someone could suggest a suitable solution.

@hiro: Those rules aren't there if you boot with nofstab.

Is any way to solve my problem ?
For security , i want to disable HDD detection while i booting from tinycore USB PenDrive and access to Internet .

[hiro]

still not clear how this could ever work in a really "secure" way.
best solution is to take out all HDDs.

Hi mbzadegan
So, you want browser access only in a GUI with no access to HDD.
You could have your bootlocal replace  /usr/bin/mnttool  and  /usr/bin/aterm  with empty scripts to disable them.
That should prevent the drives from being mounted by a user which would prevent them from being accessed.

There are various ways to access drives without ever invoking mount

Short from disconnecting hardware, recompiling the kernel so it lacks the hardware support seems like an option.

OK , But i don't find /usr/bin/mnttool and when I removed /usr/bin/aterm , still i could mount /dev/sda1 as my first HDD partition !!
I want to users could not mount HDD Partitions when they boot tinycore and access to internet ( such as light web kiosk )

Hi mbzadegan

still i could mount /dev/sda1 as my first HDD partition !!

How? Using the Mount icon? Replacing  /usr/bin/mnttool  should disable that.
Through the Terminal icon? Was it still functional? Some other method?

[mbzadegan]

i could not find /usr/bin/mnttool and only i remove /usr/bin/aterm but still i could mount with general mount command !!
#mount /dev/sda1 /hdd
Maybe it's a BUG ?
