  • strace useful for debug
  • fix new versions for pb (2.0.0 for mindi and 1.7.2 for mindi-busybox)
  • fix build process for mindi-busybox + options used in that version (dd for label-partitions-as-necessary)
  • fix typo in label-partitions-as-necessary which doesn't seem to work
  • Update to busybox 1.7.2
  • perl is now required at restore time to support uuid swap partitions (and will be used for many other thigs

in the future for sure)

  • next mindi version will be 2.0.0 due to all the changes made in it (udev may break working distros)
  • small optimization in mindi on keyboard handling (one single find instead of multiple)
  • better interaction for USB device when launching mindi manually
  • attempt to automatically guess block disk size for ramdisk
  • fix typos in bkphw
  • Fix the remaining problem with UUID support for swap partitions
  • Updates mondoarchive man page for USB support
  • Adds preliminary Hardware support to mindi (Proliant SSSTK)
  • Tries to add udev support also for rhel4
  • Fix UUID support which was still broken.
  • Be conservative in test for the start-nfs script
  • Update config file for mindi-busybox for 1.7.2 migration
  • Try to run around a busybox bug (1.2.2 pb on inexistant links)
  • Add build content for mindi-busybox in pb
  • Remove distributions content for mindi-busybox
  • Fix a warning on inexistant raidtab
  • Solve problem on tmpfs in restore init (Problem of inexistant symlink and busybox)
  • Create MONDO_CACHE and use it everywhere + creation at start
  • Really never try to eject a USB device
  • Fix a issue with &> usage (replaced with 1> and 2>)
  • Adds magic file to depllist in order to have file working + ldd which helps for debugging issues
  • tty modes correct to avoid sh error messages
  • Use ext3 normally and not ext2 instead
  • USB device should be corrected after reading (take 1st part)
  • Adds a mount_USB_here function derived from mount_CDROM_here
  • usb detection place before /dev detection in device name at restore time
  • Fix when restoring from USB: media is asked in interactive mode
  • Adds USB support for mondorestore
  • mount_cdrom => mount_media
  • elilo.efi is now searched throughout /boot/efi and not in a fixed place as there is no standard
  • untar-and-softlink => untar (+ interface change)
  • suppress useless softlinks creation/removal in boot process
  • avoids udevd messages on groups
  • Increase # of disks to 99 as in mindi at restore time (should be a conf file parameter)
  • skip existing big file creation
  • seems to work correctly for USB mindi boot
  • Adds group and tty link to udev conf
  • Always load usb-torage (even 2.6) to initiate USB bus discovery
  • Better printing of messages
  • Attempt to fix a bug in supporting OpenSusE 10.3 kernel for initramfs (mindi may now use multiple regex for kernel initrd detection)
  • Links were not correctly done as non relative for modules in mindi
  • exclusion of modules denied now works
  • Also create modules in their ordinary place, so that classical modprobe works + copy modules.dep
  • Fix bugs for DENY_MODS handling
  • Add device /dev/console for udev
  • ide-generic should now really be excluded
  • Fix a bug in major number for tty
  • If udev then adds modprobe/insmod to rootfs
  • tty0 is also cretaed with udev
  • ide-generic put rather in DENY_MODS
  • udevd remove from deplist s handled in mindi directly
  • better default for mindi when using --usb
  • Handles dynamically linked busybox (in case we want to use it soon ;-)
  • Adds fixed devices to create for udev
  • ide-generic should not be part of the initrd when using libata v2
  • support a dynamically linked udev (case on Ubuntu 7.10 and Mandriva 2008.0 so should be quite generic) This will give incitation to move to dyn. linked binaries in the initrd which will help for other tasks (ia6 4)
  • Improvement in udev support (do not use cl options not available in busybox)
  • Udev in mindi
    • auto creation of the right links at boot time with udev-links.conf(from Mandriva 2008.0)
    • rework startup of udev as current makes kernel crash (from Mandriva 2008.0)
    • add support for 64 bits udev

  • Add support for Ubuntu 7.10 in build process
  • Add USB Key button to Menu UI (CD streamer removed)
  • Attempt to fix error messages on tmp/scratch files at the end by removing those dir at the latest possible.

  • Integrate ~/.pbrc content into mondorescue.pb (required project-builder >= 0.8.7)
  • Put mondorescue in conformity with new pb filtering rules
  • Add USB support at restore time (no test done yet). New start-usb script PB varibale added where useful

    77Matt Kraai - initial writeup
    88Mark Whitley - the remix
    9 Thomas Lundquist - Added stuff for the new directory layout.
     9Thomas Lundquist - Trying to keep it updated.
     10
     11When doing this you should consider using the latest svn trunk.
     12This is a good thing if you plan to getting it commited into mainline.
    1013
    1114Initial Write
     
    1720And be sure to put it in <applet>.c. Usage does not have to be taken care of by
    1821your applet.
    19 Make sure to #include "busybox.h" as the first include file in your applet so
     22Make sure to #include "libbb.h" as the first include file in your applet so
    2023the bb_config.h and appropriate platform specific files are included properly.
    2124
    2225For a new applet mu, here is the code that would go in mu.c:
     26
     27(busybox.h already includes most usual header files. You do not need
     28#include <stdio.h> etc...)
     29
    2330
    2431----begin example code------
     
    3340 */
    3441
    35 #include "busybox.h"
    36 #include <other.h>
     42#include "libbb.h"
     43#include "other.h"
    3744
     45int mu_main(int argc, char **argv);
    3846int mu_main(int argc, char **argv)
    3947{
     
    4149    char mu;
    4250
    43     fd = bb_xopen("/dev/random", O_RDONLY);
     51    fd = xopen("/dev/random", O_RDONLY);
    4452
    4553    if ((n = safe_read(fd, &mu, 1)) < 1)
     
    6977applet that could be useful in other applets, consider putting them in libbb.
    7078
     79And it may be possible that some of the other applets uses functions you
     80could use. If so, you have to rip the function out of the applet and make
     81a libbb function out of it.
     82
     83Adding a libbb function:
     84------------------------
     85
     86Make a new file named <function_name>.c
     87
     88----start example code------
     89
     90#include "libbb.h"
     91#include "other.h"
     92
     93int function(char *a)
     94{
     95    return *a;
     96}
     97
     98----end example code------
     99
     100Add <function_name>.o in the right alphabetically sorted place
     101in libbb/Kbuild. You should look at the conditional part of
     102libbb/Kbuild aswell.
     103
     104You should also try to find a suitable place in include/libbb.h for
     105the function declaration. If not, add it somewhere anyway, with or without
     106ifdefs to include or not.
     107
     108You can look at libbb/Config.in and try to find out if the function is
     109tuneable and add it there if it is.
     110
    71111
    72112Placement / Directory
     
    78118sorted alphabetically.
    79119
    80 Add the applet to Makefile.in in the chosen directory:
     120Add the applet to Kbuild in the chosen directory:
    81121
    82 obj-$(CONFIG_MU)               += mu.o
     122lib-$(CONFIG_MU)               += mu.o
    83123
    84124Add the applet to Config.in in the chosen directory:
     
    119159algorithm in busybox.c and the Gods of BusyBox smite you. Yea, verily:
    120160
     161Be sure to read the top of applets.h before adding your applet.
     162
    121163    /* all programs above here are alphabetically "less than" 'mu' */
    122     #ifdef CONFIG_MU
    123         APPLET("mu", mu_main, _BB_DIR_USR_BIN, mu_usage)
    124     #endif
     164    USE_MU(APPLET(mu, _BB_DIR_USR_BIN, _BB_SUID_NEVER))
    125165    /* all programs below here are alphabetically "greater than" 'mu' */
    126 
    127 
    128 Documentation
    129 -------------
    130 
    131 If you're feeling especially nice, you should also document your applet in the
    132 docs directory (but nobody ever does that).
    133 
    134 Adding some text to docs/Configure.help is a nice start.
    135166
    136167
     
    138169----------------------
    139170
    140 Then create a diff -urN of the files you added and/or modified. Typically:
    141     <appletdir>/<applet>.c
    142     include/usage.c
    143     include/applets.h
    144     <appletdir>/Makefile.in
    145     <appletdir>/config.in
     171Then create a diff by adding the new files with svn (remember your libbb files)
     172    svn add <where you put it>/mu.c
     173eventually also:
     174    svn add libbb/function.c
     175then
     176    svn diff
    146177and send it to the mailing list:
    147178    busybox@busybox.net
