[squeakland] Default project on launch of Etoys-to-Go

Wed Aug 7 18:55:15 EDT 2013

Okay, may not be that simple. It did work on one Ubuntu machine but not
another.  Tried the instructions in one of Bert's links: by creating
http://askubuntu.com/questions/61448/how-to-configure-to-record-data-to-pendrive-instantlyby
creating the file below, but now dismount from file folder does not
work
:(

Will play more later and see what I find.

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"

To some of us, writing computer programs is a fascinating game. A program
is a building of thought. It is costless to build, weightless, growing
easily under our typing hands. If we get carried away, its size and
complexity will grow out of control, confusing even the one who created it.
This is the main problem of programming. It is why so much of today's
software tends to crash, fail, screw up.

When a program works, it is beautiful. The art of programming is the skill
of controlling complexity. The great program is subdued, made simple in its
complexity.
