Much space where?

bin's object tree is only about 7 MB, sbin's 17 MB.  If a typical
installation cannot measure up to 24 MB for a rebuild of bin and sbin I
guess there's worse problems on that particular installation.

And don't tell me it is needed for embedded targets, they either do
flash updates, or cross compilations.

How many libc's do you want to have on an installation? :)
And who or what guarantees that the libc you have is working correctly?

I am still trying to see the benefit over a static bin and sbin.  I
mean, come on, /bin is only 4 MB and /sbin only 12 MB.

(Funny aside though: /bin/rmail is dynamically linked on 4.8-STABLE, not
statically.  And like its manual page says: what on earth is it doing in
Same goes for /sbin/mount_smbfs, also dynamically linked.)

So give me some good reasons not to stay static?
