And more to the point, if all you know about dracut is dracut --kver 4.5, |
23 |
then you're not going to be able to _fix_ those failures. |

Some years ago I tried lvm2 as well as mdraid. I quickly ejected lvm2 |
26 |
from my system and future plans (keeping mdraid), because it was simply |
27 |
too complex for me as an admin to be confident in my ability to work with |
28 |
it without fat-fingering something, under the extreme pressure of a |
29 |
disaster recovery situation, possibly without proper access to manpages |
30 |
and other documentation due to the disaster recovery I was working thru. |
31 |

Waltdnes has a point, the same point I learned then. As a responsible |
33 |
admin, if the system's too complex to be understood well enough to be |
34 |
confident in one's ability to restore in a disaster recovery situation |
35 |
with limited or no access to manpages and similar documentation, it's too |
36 |
complex. A reasonable system is one you understand well enough to |
37 |
confidently manage it in those sorts of situations. Otherwise it's |
38 |
simply too complex for your skill level as an admin. |
39 |
|
40 |
And understanding an initr* well enough to confidently deal with a |
41 |
disaster recovery situation, possibly/likely without access to |
42 |
documentation (it's a disaster recovery, after all!) is definitely *well* |
43 |
beyond "dracut --kver 4.5" level, so he's very right to be worried about |
44 |
it. |
