Oh, that simple? I didn't know that!

Thanks for all that info. I'll file a bug one way or the other.


Anyway, here's my new workaround. There are still an issue with it, but at
least it works:

First the udev rule, placed in a file called
/etc/udev/rules.d/10-local.rules:
ATTR{product}=="Nexus 6", ATTR{serial}=="<SerialNumberOfMyPhone>",
SYMLINK+="Nexus_6", RUN+="/usr/local/bin/CreateLinkToPhone.sh"

Now the script, translated to English:
#!/bin/bash

# Create a link to the connected phone in the Media directory.

# Variables
————————————————————————————————————————————————————————————————————
# Calculate User and XDG_Runtime_Dir by searching for the phone.
Path="/run/user/"
XDG_Runtime_Dir=$(find "$Path" -maxdepth 1 -type d -regex "${Path}[0-9]+")
UserID=$(basename "${XDG_Runtime_Dir}")
User=$(getent passwd "${UserID}" | cut -d ':' -f1)

# Now just assign the right strings to all the other variables.
Media="/media/${User}"
LinkName="${Media}/${ID_MODEL}"
Target="${XDG_Runtime_Dir}/gvfs/mtp:host=%5Busb%3A${BUSNUM}%2C${DEVNUM}%5D"
LogFile="/var/log/CreateLinkToPhone"

# Main
—————————————————————————————————————————————————————————————————————————
[[ -L ${LinkName} ]] && rm -f "${LinkName}"
if [[ ${ACTION} == "add" ]]; then
ln -s "${Target}" "${LinkName}"
fi

# For the log file:
printf "%s\n        Event: %s\n    Link name: %s\n" \
"$(date +'%F %T')" \
  "${ACTION^}" \
"${LinkName}" >> "${LogFile}"
printf "Target folder: %s\n         User: %s (%s – %s)\n\n" \
"${Target}" \
$(getent passwd "${User}" | cut -d ':' -f 5 | cut -d ',' -f 1) \
"${UserID}" \
"${User}" >> "${LogFile}"
# End of script
————————————————————————————————————————————————————————————————


My log file currently looks like this (translated to English and replaced
some names and stuff), after a few times plugging and unplugging the phone:

2015-08-04 15:23:15
        Event: Add
    Link name: /media/MyUserName/Nexus_6
Target folder: /run/user/1000/gvfs/mtp:host=%5Busb%3A001%2C015%5D
         User: MyName (1000 – MyUserName)

2015-08-04 15:27:10
        Event: Add
    Link name: /media/MyUserName/Nexus_6
Target folder: /run/user/1000/gvfs/mtp:host=%5Busb%3A001%2C016%5D
         User: MyName (1000 – MyUserName)

2015-08-04 15:29:50
        Event: Add
    Link name: /media/MyUserName/Nexus_6
Target folder: /run/user/1000/gvfs/mtp:host=%5Busb%3A001%2C017%5D
         User: MyName (1000 – MyUserName)

2015-08-04 15:31:42
        Event: Add
    Link name: /media/MyUserName/Nexus_6
Target folder: /run/user/1000/gvfs/mtp:host=%5Busb%3A001%2C018%5D
         User: MyName (1000 – MyUserName)


Now I just wonder why the script doesn't run when I unplug the phone.
Shouldn't it? If not, what is the ACTION environment variable for if the
value is always ”add”…?
