I've not yet made the leap, as the benefit of faster boot really |
| 32 |
doesn't affect me between systems that're always on and laptops that |
| 33 |
typically spend 75% of their time asleep, rather than ever getting |
| 34 |
turned off, so I'm in no position to speak for or against the whole of |
| 35 |
systemd's changes... but one issue I've had with the claimed benefits |
| 36 |
is the reduction in size compared to startup scripts like |
| 37 |
/etc/init.d/sshd ... based on that service declaration above, it's a |
| 38 |
horribly unfair comparison. /etc/init.d/sshd is doing a lot more than |
| 39 |
simply starting/stopping the service and dropping all of that |
| 40 |
functionality, then claiming "these few lines serve the same purpose" |
| 41 |
isn't an equal comparison. It would still be a (notable, at that) drop |
| 42 |
in size if the shell script was redone to provide exactly the same set |
| 43 |
of features, then compared, but that size difference wouldn't have the |
| 44 |
same shock value as the comparison against 80+ lines. The argument |
| 45 |
that those functions should be handled by the service rather than the |
| 46 |
service handler is for another day, 'course. |
| 47 |
|
| 48 |
I'll eventually get around to switching to play with systemd, at the |
| 49 |
very least to learn its quirks enough to work with it, and it's very |
| 50 |
helpful to have a clearly stated set of _favorable_ comments on it |
| 51 |
(compared to the majority of less favorable commentary) to look |
| 52 |
forward to, so don't take my having one issue with the list as |
| 53 |
anything against either the list as a whole or your effort in putting |
| 54 |
all that together, as both are very much appreciated. |

Happy holidays. |
