@ -18,19 +18,12 @@ around to it some time. If you have any good ideas, please let me know.
Bugs that need fixing before the 0.44 release goes out the door:
- mkfs.minix rev 1.7 completely broke the parser. Fix it.
- 'grep foo$ file' doesn't work
- 'grep *foo file' segfaults
- ps dirent race bug (need to stat the file before attempting chdir)
- I believe that swaponoff may also be also broken (check it).
- It used to be that BusyBox tar would happily overwrite existing files on
an extraction. However, as of 0.42, BusyBox tar simply dies as soon as an
existing file is found.
- Make 'mount -a' work even when /proc isn't mounted (ugly bug).
- 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).
- implement 'ls -R'.
- "math" should also take input from stdin
- "more" doesn't accept " " to scroll by one page when BB_FEATURE_USE_TERMIOS
is not on.
