I just went through all the other lsb functions in lsb-base-logging.sh, here's
a quick report:
log_action_begin_msg CALLS log_daemon_msg
log_action_cont_msg CALLS log_daemon_msg
log_action_end_msg CALLS log_end_msg
log_action_msg DIRECT echo
log_begin_msg CALLS log_daemon_msg
log_daemon_msg UPDATED
log_end_msg UPDATED
log_failure_msg DIRECT echo
log_progress_msg DOES NOTHING
log_success_msg DIRECT echo
log_warning_msg DIRECT echo
"DIRECT echo" means a direct call to "echo" without the "-n" parameter, so
shouldn't break boot.log
"DOES NOTHING" means the function is just executing "true" (":")
"UPDATED" is the two functions I had to update to detect plymouth and store the
text in a variable until log_end_msg is called.
The rest is just calling the functions I patched.
Output seems relatively good now, it's definitely not worse than it was without
the patch.
As mentioned before the only remaining "issues" is init scripts directly
calling echo (can't really do anything about that) and scripts like apparmor
doing:
1) log_daemon_msg
2) log_action_msg
3) log_end_msg
Where the old behaviour would have been:
1) Show something like " * Starting AppArmor profiles"
2) Add: "Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox"
3) Finishes the line (actually the next line due to 80 chars limit): "[ OK ]"
And the new one is:
1) Put " * Starting AppArmor profiles" in a variable, doesn't print anything
2) Shows" Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox"
3) Shows " * Starting AppArmor profiles [ OK ]"
