Bugs that need fixing:
|
||||
|
||||
- "more" doesn't accept " " to scroll by one page when BB_FEATURE_USE_TERMIOS
|
||||
is not on.
|
||||
- doc / website updates to tell what the real mailing list is for busybox.
|
||||
- fix 'cp' (or test suite script) so that it passes the test suite.
|
||||
|
||||
These could get done before the 0.44 release if we have time, but we won't
|
||||
hold up the 0.44 release just because of these:
|
||||
|
||||
- ps dirent race bug (need to stat the file before attempting chdir)
|
||||
- Make 'ln -s /tmp/file .' work the way GNU ln does (i.e. makes a link to
|
||||
/tmp/file in the current directory, rather then trying and failing to create
|
||||
a symlink named "." in the current working directory).
|
||||
- Prune sfdisk
|
||||
- Graft fdisk
|
||||
- Graft fdisk instead
|
||||
|

These will be deferred til after 0.44 is released. We will rework these to use
|
||||
libc regex functions instead (as per the mailing list discussion):

Linux 2.4.x kernels
|
||||
|
||||
BusyBox 0.45 currently will not work with the Linux 2.4.x kernels.
|
||||
I know of the following problems:
|
||||
|
||||
1) The sysinfo syscall has changed what it does (binary incompatable), breaking
|
||||
init and free.
|
||||
2) BusyBox NFS support is broken with 2.4.x (needs to be adjusted for NFSv3 and
|
||||
kernel header changes).
|
||||
3) mount,umount,and df are all broken by the "none" entries for fake filesystems
|
||||
such as the shared mem one. Al Viro claims these will be disappearing soon...
|
||||
|
||||
I made a kernel patch that reverts the sysinfo changes
|
||||
http://kernelnotes.org/lnxlists/linux-kernel/lk_0006_01/msg00619.html
|
||||
|
||||
and I have been fighting with Alan Cox to get these changes fixed in a binary
|
||||
compatable way, but Alan has so far not been very receptive. I am planning on
|
||||
appealing to Linus (when he gets back from vacation) and then going with
|
||||
whatever he decides...
|
||||
|
||||
So my thought is, 2.4.x just isn't ready for BusyBox to target it, and even if
|
||||
it was, BusyBox isn't ready yet either. Seems to me like this will not be
|
||||
ready for a while, and we should just not worry about it yet.
|
||||
|
||||
As long as I have BB_FEATURE_NFSMOUNT turned off, everything compiles cleanly
|
||||
for me with linux2.4.0test1-ac22-riel (i.e. I don't see the freeramdisk.c
|
||||
problem you reported). I use Debian potato (gcc 2.95.2, GNU libc 2.1.3).
|
||||
Of course, as noted above, compiling != working.
