Default eselect sh set dash?

Hi list!

Now that eselect-sh has been stabilized, I'm wondering if anyone has
tried setting dash as the /bin/sh symlink. Any experiences?

Thanks in advance!

I've been using dash as my /bin/sh for a while now. I've had it installed since
June 2009, I suppose I've had the symlink set for the same length of time.

Pretty much all incompatibilities I encountered are fixed now, stuff like
openrc introducing bashisms (what fun! I never used the debug option of an init
script before or since), or the Audacity build system having #!/bin/sh but
using bashisms. I seem to recall that I have one package installed that has this
problem and requires changing the symlink temporarily, but I don't remember
which. It might have been fixed by now, though.

Also, the old mysql-init-scripts-1.2 package requires bash, in case that matters
to you.

So I don't think you should expect any problems (save for the rare exception),
and for me there was a noticeable speedup with the init system (also reported
by Flameeyes in his blog).

Hi Marc,

thanks for the info! I've tried it on one of my systems and in my
measurements, it definitely scraped off a few seconds of the reboot cycle.

The dmcrypt init script also has a single bashism. A bug about this has
been open for quiet some time now:

I suggest that anyone who wants to switch tries something like this
before rebooting to see if the init scripts can be parsed by dash:

for i in /etc/init.d/*; do printf '%s ' "$i"; "$i" status; done
