just upgraded my distro from wheezy to Jessie
I used to get /media
now I get /media/root
how do I change it back
I already have a autoexec.sh containing udisks that does it for me but I am annoyed that I don't understand this better.
do not talk about editing /etc/fstab. that's not not where I am coming from.
I hated grub2 till I rewrote it.
I added remastersys and a custom menu
I also have pcmanfm create and delete my samba shares, lots of fun.

Under what circumstances to you get "/media/root"? Specifically, is it when mounting removable devices as root?

I always have and will auto-login as root. for convenience. not interested in doing any typing for passwords or logins ever.

Welcome to LinuxQuestions.

Not enough information provided and like frankbell assume this is about automounting USB devices. By default udisks automatically mounted removable media to /media/label and udisks2 automatically mounts to /media/username/label. Supposedly you can add a udev rule to change it back to /media.

sorry about the lack of detail, a post went missing
the partitions mounting in the wrong place are all of them.
removable or otherwise.
however you are already going in a direction I like when you mention udev rules.
I will look in /etc/udev and see If I can do it from here

I deleted udisks2, the annoying hard disk mounts are gone
but they don't show unless

/usr/bin/udisks --mount /dev/sda2
/usr/bin/udisks --mount /dev/sda5
/usr/bin/udisks --mount /dev/sdb1
/usr/bin/udisks --mount /dev/sdb5
/usr/bin/udisks --mount /dev/sdc1
/usr/bin/udisks --mount /dev/sdc5
/usr/bin/udisks --mount /dev/sdd1
/usr/bin/udisks --mount /dev/sdd5


is in my autoexec.
Usb disks are automatically mounted to /media. I am happy and so are my spin users

I must mention this is the most direct and useful advice I have ever received.
Anyway I can avoid the autoexec entries?

from the clues I got on this forum, many thanks moderator and frankbell

the perfect answer turned out to be

create
/etc/udev/rules.d/20-media-by-label-auto-mount.rules

which contains everything below

KERNEL!="sd[a-z][0-9]", GOTO="media_by_label_auto_mount_end"

# Import FS infos
IMPORT{program}="/sbin/blkid -o udev -p N"

# Get a label if present, otherwise specify one
ENV{ID_FS_LABEL}!="", ENV{dir_name}="%E{ID_FS_LABEL}"
ENV{ID_FS_LABEL}=="", ENV{dir_name}="usbhd-%k"

# Global mount options
ACTION=="add", ENV{mount_options}="relatime,sync"
# Filesystem-specific mount options
ACTION=="add", ENV{ID_FS_TYPE}=="vfat|ntfs", ENV{mount_options}="$env{mount_options},utf8,uid=1000,gid=1000,umask=002"

# Mount the device
ACTION=="add", RUN+="/bin/mkdir -p /media/%E{dir_name}", RUN+="/bin/mount -o $env{mount_options} /dev/%k /media/%E{dir_name}"

# Clean up after removal
ACTION=="remove", ENV{dir_name}!="", RUN+="/bin/umount -l /media/%E{dir_name}", RUN+="/bin/rmdir /media/%E{dir_name}"

# Exit
LABEL="media_by_label_auto_mount_end"

found a better answer
Mount to /media (udisks2)
By default, udisks2 mounts removable drives under the ACL controlled directory /run/media/$USER/. If you wish to mount to /media instead, use this rule:


/etc/udev/rules.d/99-udisks2.rules
contains

# UDISKS_FILESYSTEM_SHARED
# ==1: mount filesystem to a shared directory (/media/VolumeName)
# ==0: mount filesystem to a private directory (/run/media/$USER/VolumeName)
# See udisks(8)
ENV{ID_FS_USAGE}=="filesystem|other|crypto", ENV{UDISKS_FILESYSTEM_SHARED}="1"
