rpm: respect BB_SYSTEMROOT

2026-07-02T12:11:37+00:00

Update the 'rpm' applet so it also respects the BB_SYSTEMROOT environment variable. Replace chdir_system_drive() with xchdir_system_drive(), which exits on failure to change directory. Saves 32-36 bytes. (GitHub PR #603) Signed-off-by: Ron Yorston

dpkg: update prefix (#603)

2026-07-02T10:54:38+00:00

* dpkg: update prefix The prefix now works properly with BB_SYSTEMROOT as it no longer writes everything with a prefixed / For example, with BB_SYSTEMROOT=C:/somepath, the /var/lib/dpkg directory is now underneath that, rather than the root of that drive. Also added handling so that the extracted files are also there. * dpkg: prefix updates For clarity, the .list files now always include leading slashes, matching what happens in upstream. There is then special handling under remove_file_array to turn them back into relative paths. The handling assumes that files can be both, since it does get called with some relative paths. Adds 14-54 bytes.

ash: only report background jobs in root shell

2026-06-30T16:50:30+00:00

Background jobs were being reported in shells other than an interactive, top-level shell. Suppress this unnecessary report. Adds 16 bytes. Signed-off-by: Ron Yorston

ash: only copy jobtab if needed for job hack

2026-06-30T16:31:20+00:00

This script: #!/bin/bash ( ( true ) & ( true ) & ( true ) & ( true ) & ( true ) & ) resulted in a crash. The problem was introduced by commit 7b692ddf0c (ash: improved support for jobs built-in). This commit copies the job table into child shells for use by the 'jobs' built-in. The crash happens because when the job table is cleared in the child it becomes available for reuse. If only four jobs are required this is OK but going over four causes the table to be reallocated. This doesn't work because in the child it's in shared memory. The fix is not to pass the job table to the child unless it's required by the 'jobs' built-in. This is also more efficient. Adds 0-16 bytes. (GitHub issue #604) Signed-off-by: Ron Yorston

join: code shrink

2026-06-30T08:07:06+00:00

Adopt some BusyBox idioms in join_main(). In particular: - The '-a' and '-v' options are mutually exclusive. Enforce this in getopt32() instead of by hand. Also, since they're mutually exclusive we don't need a distinct list for each. - Control some clean-up code with ENABLE_FEATURE_CLEAN_UP. There are also a few cosmetic changes. Saves 204-256 bytes.

build system: allow bloatcheck to work (a bit) for llvm

2026-06-30T07:45:15+00:00

'make bloatcheck' didn't work in the ARM build because it didn't handle the different output formats of llvm's 'objdump' and 'nm'. Allow for 'objdump -h' printing 5 rather than 7 fields. This at least gets us some output. 'nm' always seems to print symbol sizes of zero, though, which isn't very useful. Signed-off-by: Ron Yorston

win32: tweak bitmap icon appearance

2026-06-26T11:48:05+00:00

Make the corners of the symbolic bitmap icon look more rounded. Signed-off-by: Ron Yorston

win32: shrink bitmap icons

2026-06-23T15:06:39+00:00

Reduce the colour depth of the bitmap icons from 24-bits colour/ 8-bit alpha to 8-bit colour/1-bit alpha for aterm.ico and 1-bit colour/1-bit alpha for sterm.ico. This reduces the size of the standard builds by 21KB. The builds targeting Windows 10/11 already used smaller PNG icons. Signed-off-by: Ron Yorston

sync: handle certain edge cases

2026-06-23T07:05:34+00:00

Recent changes to our mntent routines added support for Windows volume names. If such a name is available use it in our sync(2) implementation to flush file buffers. Failing that, use the drive letter as before. This handles edge cases where only one or other of the volume name or drive letter is available. Adds 32 bytes. Signed-off-by: Ron Yorston

test: fix POSIX build

One Windows-specific line of code wasn't protected by #ifdef. Signed-off-by: Ron Yorston
