Automount USB rules.d Query

[MadCat]

Hello. I am currently trying to automatically have USB Devices automounted using rules under the rules.d folder. I have currently tried making a automount.rules (Which I read from another website) and adding the following below to it. But, I take this wont work because Tiny Core does not come with pmount?

# automounting usb flash drives
# umask is used to allow every user to write on the stick
# we use --sync in order to enable physical removing of mounted memory sticks -- this is OK for fat-based sticks
# I don't automount sda since in my system this is the internal hard drive
# depending on your hardware config, usb sticks might be other devices than sdb*
ACTION=="add",KERNEL=="sdb*", RUN+="/usr/bin/pmount --sync --umask 000 %k"
ACTION=="remove", KERNEL=="sdb*", RUN+="/usr/bin/pumount %k"
ACTION=="add",KERNEL=="sdc*", RUN+="/usr/bin/pmount --sync --umask 000 %k"
ACTION=="remove", KERNEL=="sdc*", RUN+="/usr/bin/pumount %k"

Anybody out there?

I am not completely sure what you are trying to do, but

To mount usb drives at startup, add mount commands to /opt/bootlocal.sh.

Hi MadCat
I'm not versed in writing udev rules but if the rules you have listed are correct then changing
pmount and pumount to mount and umount should make it work.

Im trying to get it that when you plug in a USB Device it automounts the device without having to restart Tiny Core, or am I totally on the wrong track here? :/

Hi MadCat
I got what you are trying to do, if my previous suggestion does not work, here is a post that goes
into some details of udev rules.

Unfortunately that is only for startup "Which works btw". But I need to figure out how to get it to mount WITHOUT having to restart the terminal first. Any ideas?

Did you try substituting mount for pmount and umount for pumount in this?

Code: [Select]

ACTION=="add",KERNEL=="sdb*", RUN+="/usr/bin/pmount --sync --umask 000 %k"
ACTION=="remove", KERNEL=="sdb*", RUN+="/usr/bin/pumount %k"
ACTION=="add",KERNEL=="sdc*", RUN+="/usr/bin/pmount --sync --umask 000 %k"
ACTION=="remove", KERNEL=="sdc*", RUN+="/usr/bin/pumount %k"

Unfortunately doing it THAT way does not work. And mount/umount is sitting under /bin/mount and /bin/umount I believe. Not /usr/bin/mount and /usr/bin/umount. Eitherway, that only works if u plug in a Flash Drive and startup the terminal. Im needing a solution so that when I plug in Flash Drives while the terminal is on it auto mounts them without me having to mount /mnt/bla bla

Hi MadCat
As I said, I'm not versed in udev rules, but try this.

ACTION=="add",KERNEL=="sd[b-z][0-9]", RUN+="sudo /bin/mount --sync /dev/%k mnt/%k"
ACTION=="remove", KERNEL=="sd*", RUN+="bin/umount -l %k"

Then open a terminal and enter this  udevadm control --reload-rules
Plug in a memory stick and see if it is accessible under /mnt

This presumes that you have an internal drive labeled  sda  and wish to exclude it from hot plugging.
If that's not the case then  sd[b-z][0-9]  should be  sd[a-z][0-9]

Check 98-tc.rules in /etc/udev/rules.d

KERNEL=="ram*", SUBSYSTEM=="block", GOTO="tc.rules_end"
KERNEL=="loop*", SUBSYSTEM=="block", GOTO="tc.rules_end"
ACTION=="add",      SUBSYSTEM=="block",   RUN+="/bin/sh -c '/usr/sbin/rebuildfstab'"
ACTION=="remove",   SUBSYSTEM=="block",   RUN+="/bin/sh -c '/usr/sbin/rebuildfstab'"
LABEL="tc.rules_end"

This rule handles block device add and remove executing rebuildfstab. Look like a good starting point.

Replace it with a new rule set:

KERNEL=="ram*", SUBSYSTEM=="block", GOTO="tc.rules_end"
KERNEL=="loop*", SUBSYSTEM=="block", GOTO="tc.rules_end"
ACTION=="add",      SUBSYSTEM=="block",   RUN+="/bin/sh -c '/usr/local/sbin/xxx %k'"
ACTION=="remove",   SUBSYSTEM=="block",   RUN+="/bin/sh -c '/usr/local/sbin/yyy %k'"
LABEL="tc.rules_end"

Here we are calling two shell scripts. Do not forget to reload rules with

sudo udevadm control --reload-rules

Now, the related scripts.

xxx is mounting partition after rebuildfstab:

#!/bin/sh
rebuildfstab
sleep 3
mount /dev/$1 /mnt/$1

yyy is executing umount and removes the mounting directory in /mnt:

#!/bin/sh
umount /mnt/$1
sleep 1
rmdir /mnt/$1
rebuildfstab

sleep commands are for safety, maybe it can be removed or delay changed-

Try, it works. Simple, isn't it ?

And mount/umount is sitting under /bin/mount and /bin/umount I believe. Not /usr/bin/mount and /usr/bin/umount.

Have you considered symlinking?

[tinypoodle]

When you plan to automount USB flash drives, have you also planned for the case of filesystems being unclean?

Which filesystem types do you plan to automount?

[MadCat]

KERNEL=="ram*", SUBSYSTEM=="block", GOTO="tc.rules_end"
KERNEL=="loop*", SUBSYSTEM=="block", GOTO="tc.rules_end"
ACTION=="add",      SUBSYSTEM=="block",   RUN+="/bin/sh -c '/usr/local/sbin/xxx %k'"
ACTION=="remove",   SUBSYSTEM=="block",   RUN+="/bin/sh -c '/usr/local/sbin/yyy %k'"
LABEL="tc.rules_end"

Done so. Created 2 files called xxx.sh and yyy.sh in /usr/local/sbin as it was required. So now my 98-tc.rules basically looks like the following below.

KERNEL=="ram*", SUBSYSTEM=="block", GOTO="tc.rules_end"
KERNEL=="loop*", SUBSYSTEM=="block", GOTO="tc.rules_end"
ACTION=="add",      SUBSYSTEM=="block",   RUN+="/bin/sh -c '/usr/local/sbin/xxx.sh %k'"
ACTION=="remove",   SUBSYSTEM=="block",   RUN+="/bin/sh -c '/usr/local/sbin/yyy.sh %k'"
LABEL="tc.rules_end"

sudo udevadm control --reload-rules

Then added the following to the 2 files

xxx.sh

#!/bin/sh
rebuildfstab
sleep 3
mount /dev/$1 /mnt/$1

yyy.sh

#!/bin/sh
umount /mnt/$1
sleep 1
rmdir /mnt/$1
rebuildfstab

Result. It doesn't work... It doesn't even seem to get as far as rebuildfstab since no drives are even recognized when you insert a USB... What a mission to get USB to automount :S
