Second the various init scripts that lfs currently use are mixed /bin/bash and /bin/sh. What vendor supplied script? We are talking lfs/blfs here. Why would a vendor script source init-functions? It most likely wouldn't work anyway if it did. sh compliant in what way? POSIX? UNIX? The sh used by lfs (gnu bash) is what I call sh++ as it uses and accept most bash builtins. If you test my changes you will see that they run the same sourced by a script using /bin/sh or /bin/bash (I tested for that). And yes I do know that LSB requires the scripts to be /bin/sh, but we are again talking lfs here. BTW is dash even in the BOOK? I have no use for dash or ash. If I was to use dash and posted here I would simply be told your distro your rules, so after all, why would that not apply here for some one wanting to use dash or a vendor script? -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.
