Description Zac Medico gentoo-dev 2021-11-06 00:06:59 UTC
Continued from bug 727832 comment 6, bash_command_not_found_re does not handle the case where sh is busybox:

> $ ash -c 'foo'
> ash: foo: not found

lib/portage/package/ebuild/    bash_command_not_found_re = re.compile(
lib/portage/package/ebuild/        r"(.*): line (\d*): (.*): command not found$"
Comment 1 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2021-11-06 07:33:07 UTC
If sh is busybox, then command-not-found detection not working properly is the least of our worries.  IIRC busybox sh isn't POSIX-compliant.
Comment 2 Fabian Groffen gentoo-dev 2021-11-06 07:58:09 UTC
While at it:

% dash -c foo
dash: 1: foo: not found
Comment 3 orbea 2022-06-18 17:22:55 UTC
Another one...

$ mksh -c 'foo'
mksh: foo: inaccessible or not found

I'll add a depends-on for portage-3.0.59, but we shouldn't close this on release given busybox/mksh isn't covered. Not that I really think busybox is a suitable /bin/sh.
Comment 6 Eli Schwartz gentoo-dev 2023-12-20 14:11:20 UTC
I'll also note that I kinda have zero interest in mksh on a personal level, and while I do like busybox as a general thing I have *negative* interest in it as a general purpose /bin/sh and would strongly prefer refusing to support it.

Someone other than me should add support for mksh though. :D
