Hi, since the whole discussion got somehow sidetracked on where and if |
| 2 |
to install for everybody the rc system specific files for everybody |
| 3 |
(that should be an implementation detail for the specific dohelper |
| 4 |
IMHO), I'm back to the other part of it: switching the actual init |
| 5 |
implementation. |

# WHY (not just edit your bootloader) |
| 8 |
|
| 9 |
Since efi at least some people started to put in the kernel the bootargs |
| 10 |
and we have at least few new options brewing for init, some are |
| 11 |
small impact (bootchar, bb-init-openrc and runit-openrc) some are more |
| 12 |
invasive (runit and systemd). |
| 13 |
|
| 14 |
In those setup changing bootargs requires a kernel rebuild and some |
| 15 |
effort, while the eselect approach stays completely transparent. |
| 16 |
|
| 17 |
For some switch we might not have just to change the init binary bit |
| 18 |
also to do some other changes (e.g. use a different format for inittab) |
| 19 |

# KEYPOINTS |
| 21 |
|
| 22 |
- /sbin/init (or whatever linux currently calls by default with top |
| 23 |
priority) should be either a symlink to the actual implementation or a |
| 24 |
wrapper such as our gcc one. I like better the latter since it is |
| 25 |
overall safer. The former might or might work since linux has some |
| 26 |
fallback capabilities but hadn't been tested. |
| 27 |
|
| 28 |
- init gets effectively switched only at boot/reboot, eselect init must |
| 29 |
keep track of the current active init and make sure the current init |
| 30 |
configuration is used till the system reboots, if we use the wrapper |
| 31 |
approach, it would pick up what's the new init at boot and that would be |
| 32 |
enough for simple cases, hooks on reboot are still needed for more |
| 33 |
complex ones. |
| 34 |
|
| 35 |
- we could try to not have the changes to the current init systems |
| 36 |
ebuild or reduce them to the bare minimum (e.g. not overwrite /sbin/init) |
| 37 |
|

# FOCUS |
| 39 |
|
| 40 |
My interest is mostly if not all on bb-init-openrc and slightly on |
| 41 |
runit-openrc. |
| 42 |
|
| 43 |
There are enough people involved in systemd and since I still consider |
| 44 |
it a dangerously frail implementation of a bad idea is better if I do |
| 45 |
not touch it at all. |
| 46 |
|
| 47 |
My system with stock openrc gets from linux start to graphical login in |
| 48 |
less than 6s and I'm not using Gnome so I do not have any reason to use |
| 49 |
it beside comparing. |
