Busybox is pretty much essential if you’re using a small, embedded linux. It’s small footprint and complete replication of most of coreutils (and a bunch of other packages) makes it great. All you end up with are a bunch of symlinks.
The problem is, though, that pretty much all the commands are ‘slightly different‘. They don’t take long options. Help is not helpful (I’ve regularly had to look at the source to tell what’s the problem).
The real problem comes when you decide you want to rip it out of your system. All those minor things that had to be changed to work under the busybox system now have to be re-checked under coreutils and family.
Fun for all the family.
If it wasn't for carbon-14, I wouldn't date at all
