This is because bash is rather unusual on embedded Linux systems. At
least on small devices, bash has a farily targe foot print, so in most
cases a simpler shell is used. For example, the default in Buildroot is
to use the 'ash' shell implemented by Busybox.

Comparing with a desktop distribution, if that's what you did, is
misleading. Desktops distributions run on machines with large of disks
and RAMs, and

However it is perfectly fine if you want to use bash on your embedded
system, and that's why Buildroot has a 'bash' package.

Mmh, I realize now it's probably wise if we add back the bash-specific
lines, but in package/bash/bash_profile, and of course install that
file. This would give back bash features to bash users, out of the box,
and without cluttering the rootfs for other users.

Why don't you try to do it yourself, and make your first code
contribution to Buildroot?
