# Overall, this script works quite nicely, but please help to
|
|
# make this script more robust!
|
|
|
|
# Testers: need help to ensure this script remains POSIX compliant.
|
|
# Some distros do not use bash as a default shell.

|
|
#===============================================================
|
|
# This is a modest attempt to migrate a KDE3 profile to Trinity.
|
|
# If $HOME/.trinity exists then skip this one-time migration.
|
|
|
|
# Can this script be run from within starttde?
|
|
# Challenge: to run this script from within starttde requires
|
|
# graphical dialog boxes. When is the underlying TDE system
|
|
# sufficiently operational in the starttde script to use KDialog?
|
|
# If KDialog is unavailable then that leaves xmessage, which is
|
|
# ugly although possibly adequate.
|
|
|
|
# If KDialog is unavailable until after $HOME/.trinity exists, such
|
|
# as after running KPersonalizer, then this script will not help.
|
|
# Also, KPersonalizer automatically creates a skeleton profile directory
|
|
# when launched, as does some command line tools such as kconf_update.
|
|
#
|
|
# Additionally, this script was written mainly from a command line
|
|
# login perspective. This script and concept needs testing and
|
|
# improvements to support graphical login systems.
|
|
|
|
#===============================================================
|
|
# Known Quirks:
|
|
# When testing the same user account between two different systems, such
|
|
# as a real and virtual machine or two different physical machines,
|
|
# after a migration KMix is always muted because the sound devices differ.
|
|
|
|
# Not sure, but forced window sizes saved in kwinrulesc seem to break after
|
|
# a migration.
