We're reading the path of the init file to boot from a file, we start the executable at that path; no writes are involved here. The only problem left here is that some init systems need a specific version of the inittab file, although this can likely be changed in late shutdown as the only exception to this approach.

We should avoid maintenance burden where we can; we can't also force things upon them, as you can see in other ML threads here. Init systems are quite necessary in Gentoo, let's not risk losing their maintainers. That being said; if there are exceptions to the approach we end up taking, we need to put these somewhere. It kind of depends on how we will integrate the init system approach in the Portage tree. -- With kind regards, Tom Wijsman (TomWij) Gentoo Developer E-mail address : tom...@gentoo.org GPG Public Key : 6D34E57D GPG Fingerprint : C165 AF18 AB4C 400B C3D2 ABF0 95B2 1FCD 6D34 E57D
