Romain, All,
On 2018-01-17 18:44 +0100, Romain Naour spake thusly:
> When mksh is selected, /bin/mksh is not added to /etc/shells
> (see man shells). So, login tools like dropbear reject the ssh
> connexions for users using mksh as shell in /etc/passwd.
>
> buildroot authpriv.warn dropbear[853]: User 'kubu' has invalid shell, rejected

Since mksh is a generic package, you could just include that code
within MKSH_ISNTALL_TARGET_CMDS, and do without the hook:
define MKSH_INSTALL_TARGET_CMDS
$(INSTALL) -m 0755 -D $(@D)/mksh $(TARGET_DIR)/bin/mksh
grep -qsE '^/bin/mksh$$' $(TARGET_DIR)/etc/shells \
|| echo "/bin/mksh" >> $(TARGET_DIR)/etc/shells
endef
