It seems there is some demand for this. http://www.busybox.net/FAQ.html#standalone_shell https://bugs.gentoo.org/show_bug.cgi?id=525586#c4
Created attachment 394636 [details, diff] Ebuild patch
see also https://bugs.gentoo.org/show_bug.cgi?id=501092#c3 - that was about removal of ar, which you now (inadvertently?) removed, along with tune2fs, mkfs.reiser, uncompress, fdisk support for GPT partitions, ... I still don't see how the change of one setting ( TFTP Debug as requested in #525586 ) turned into a change of 100 settings. The FAQ seems horribly outdated to me, by the way. Mounting /proc works just fine. Gentoo's busybox used to be great. Please reconsider.
(In reply to Andreas Klauer from comment #2) > Gentoo's busybox used to be great. Please reconsider. If you need to customize it, there is always the savedconfig feature.
If you consider reverting to the allyesconfig, I would at least like to know why and consult upstream about it. And by what I mean which configuration options in busybox. I hope adding this will cover most use cases.
the default busybox build is designed to give you a rescue shell. the standalone shell feature is fairly critical to that, hence it is enabled by default. if you want to disable this feature, then use savedconfig to do so. i'm not sure how the referenced bugs show that there is sufficient demand to warrant turning it off by default.
