3 | The scripts contianed in this directory are a complete rewrite of the
|
---|
4 | boot scripts from LFS-6.1 (updated for LFS-SVN about 2008-05-31). As is
|
---|
5 | usually the case with a rewrite, there have been many changes:
|
---|
6 |
|
---|
7 | AS OF 20080907, THESE SCRIPTS REQUIRE THE NEW initd-tools PACKAGE.
|
---|
8 | Dan Nicholson has recently released an initd-tools package that contain
|
---|
9 | LSB compliant install_initd and remove_initd programs written in C.
|
---|
10 | See the INSTALL file for installation instructions.
|
---|
11 |
|
---|
12 | LSB Version 3.2 Compliant Scripts - Immediately noticable are the LSB headers
|
---|
13 | in the rc.d scripts themselves. Each script contains a usable header to
|
---|
14 | allow for automating both the installation of, and determining proper
|
---|
15 | execution order for the startup scripts. These values can also be used
|
---|
16 | directly in parallel boot setups. Additionally, messages are displayed in
|
---|
17 | one single write to the screen, after exit status is determined, so that
|
---|
18 | they can be used in parallel setups. I am not sure if this was the only
|
---|
19 | barrier to auto language translation in the previous bootscripts. Further,
|
---|
20 | the messages are created from parts and only written to the screen in a
|
---|
21 | single command, so maybe no help at all WRT translated boot messages.
|
---|
22 |
|
---|
23 | Distribution Independent - this original goal for the LFS scripts has been
|
---|
24 | stretched even further by providing both a global rc config file that
|
---|
25 | contains (generally) static values, and a new rc.site config file to allow
|
---|
26 | customization of messages as diplayed to the end user during the boot
|
---|
27 | process. The format of messages printed to the screen is adjustable
|
---|
28 | here. As well, the other options that were available in the previous
|
---|
29 | versions of the lfs-bootscripts, and additional options as discussed below,
|
---|
30 | are configurable by the /etc/sysconfig/rc.site file.
|
---|
31 |
|
---|
32 | Single Environment - The rc script has been rewritten completely to allow a
|
---|
33 | single source of the boot configuration per runlevel change. This config
|
---|
34 | is inherited from rc's environment as opposed to being sourced everytime a
|
---|
35 | script is run. This results in a negledgable decrease in boot time, but
|
---|
36 | it is just better in principle.
|
---|
37 |
|
---|
38 | Boot Logging - The previous incarnation of the boot log didn't begin
|
---|
39 | recording events until the root filesystem was mounted read/write. This has
|
---|
40 | been corrected by providing a tempfs mount immediately after init hands
|
---|
41 | control to the rc script. The bootlog is generated on the tempfs and then
|
---|
42 | passed to the log file before login. Additionally, shutdown events are no
|
---|
43 | longer recorded in the bootlog. They were pretty much useless and it really
|
---|
44 | wasn't what I'd call a *boot* log. Boot logging is on by default and is
|
---|
45 | configurable in the /etc/sysconfig/rc.site file.
|
---|
46 |
|
---|
47 | Interactive Boot - This feature has been included by default, and is a
|
---|
48 | little more polished than my previous attempt. It does introduce a two
|
---|
49 | second delay in the boot process (so that you have time to press a button
|
---|
50 | to select interactive mode). This time value, and the option prompt itself,
|
---|
51 | is configurable in the /etc/sysconfig/rc.site file.
|
---|
52 |
|
---|
53 | Path changes - The base directory for the bootscripts is now /etc, not
|
---|
54 | /etc/rc.d. This is mostly to conform with mainstream distros, but other
|
---|
55 | boot methods do expect that /etc/init.d is the location of bootscripts.
|
---|
56 | Some distros provide a rc.d direcorty with symlinks to the rc*.d and init.d
|
---|
57 | directories, I have not done that. /etc is the location now, get your
|
---|
58 | flying fingers accustomed to it! Of course, this is still configurable in
|
---|
59 | /etc/sysconfig/rc.site, and if the change is too great, I'll put it back.
|
---|
60 | I've also removed the rcsysinit.d directory and replaced it with rcS.d.
|
---|
61 |
|
---|
62 | LSB Functions - The previous lfs-bootscripts sourced a functions file
|
---|
63 | located at /etc/rc.d/init.d/functions. This file has been renamed
|
---|
64 | $distro-functions to segregate it from the old. The name is configurable
|
---|
65 | by the rc.site configuration file. LSB defined functions are used where
|
---|
66 | possible, but the $distro-functions file provides, easy to use wraper
|
---|
67 | functions that start/stop/reload/force-reload/restart programs, evaluate
|
---|
68 | the numerical LSB return values, and print status messages to the screen.
|
---|
69 | Both LFS functions and LSB functions are documented directly in the scritps
|
---|
70 | located at /etc/init.d/$distro-functions and /lib/lsb/init-functions
|
---|
71 | respectively.
|
---|
72 |
|
---|
73 | Pretier - Yeah, I just couldn't handle all the grey text... By default,
|
---|
74 | successful boot messages are prefixed with a single green astrik character,
|
---|
75 | warning messages with two yellow astirks, and failures are prefixed with
|
---|
76 | three red astriks. This just provides a second 'quick glance' status when
|
---|
77 | watching the boot messages fly by. Again, the prefixes are configurable (or
|
---|
78 | completely removable) in the /etc/sysconfig/rc.site file.
|
---|
79 |
|
---|
80 | Complete Rewrite - Yep. That doesn't mean that code wasn't reused when
|
---|
81 | possible, so Alexander, Bryan, Dan, Gerard, Jeremy, Jim, Mathias, Matthew,
|
---|
82 | Nathan, and countless other contributors (whose names I've forgotten and will
|
---|
83 | promptly be reminded of (please)) are due credit for these as well. That
|
---|
84 | said, at very least, this is a complete reorganisation that I've tested to
|
---|
85 | the best of my ability, but there probably are some hidden bugs that will
|
---|
86 | come to lite when used more frequently. Please give me a shout _when_ you
|
---|
87 | find them.
|
---|
88 |
|
---|
89 | Thanks.
