rebaseall (which is a wrapper around rebase) _cannot_ rebase an in-use
.dll. Dash has fewer in-use dlls than bash. Therefore, dash is the
(much) better choice for rebase.
By the way, the Bourne shell is pretty much obsolete. On Solaris,
/bin/sh is still the Bourne shell, but on every other system, /bin/sh
aims to be POSIX-compatible (the historic Bourne shell does not comply
with POSIX). And for portability reasons, you are better off writing a
POSIX-compatible script that can use /bin/sh rather than requiring
/bin/bash.
I'm also entertaining the notion of following Debian's lead and
switching /bin/sh to dash, since dash is noticeably faster than bash if
your script is POSIX-conforming. Not very seriously yet, but it's not
out of the question.

Please report bugs in the dash man page upstream to the dash development
list.
