Two patches which allow a user to bypass files created with doman and |

dodoc in FEATURES: |

Quick background/inspiration: |
| 10 |
|
| 11 |
I found myself having to make an initrd suitable to do PXE boots for |
| 12 |
our business and educational clusters. I was exploiting the ever so |
| 13 |
useful ROOT option for portage to emerge packages into the initrd |
| 14 |
build directory. However, because this was an initrd being sent over |
| 15 |
the network, total size was important. |
| 16 |
|
| 17 |
At larger sizes the loading the initrd would actually cause a kernel |
| 18 |
panic on pivoting root...whether this was a result of a kernel config, |
| 19 |
a set maximum size limit, or something else I'm not exactly sure of. |
| 20 |
|
| 21 |
Looking at the output of du, I started first by removing the man and |
| 22 |
documentation files. This brought the size of my final initrd down |
| 23 |
significantly (~287MiB to ~242MiB). |
| 24 |
|
| 25 |
Possible issues/bigger picture: |
| 26 |
|
| 27 |
While I was making the changes to doman and prepman, I kept thinking |
| 28 |
of how this really is part of a bigger picture, [I think] maybe the |
| 29 |
whole minimal concept should be abstracted out of USE (for packages |
| 30 |
that have it) and be part of FEATURES (for all packages). |
| 31 |
In my case because I was using ROOT in portage to build out an initrd, |
| 32 |
I didn't really need or want man or documentation for the packages I |
| 33 |
was putting in. |
| 34 |
|
| 35 |
At the end of the day, maybe there should be a specific mix of |
| 36 |
FEATURES such as "nodoc noman" and/or a granular mix of "minimal" |
| 37 |
which encompasses the previous+more. Obviously it's open for a lot of |
| 38 |
discussion and the patches attached should/would probably not be a |
| 39 |
final solution...the goal was that this would be a start. |
| 40 |
|
| 41 |
We've been using this patch and it's worked out for us well. Your |
| 42 |
mileage may vary, if it does, please say something! :-) |

PS Sorry to the devs I was working with (you know who you are :-) for |
| 48 |
my inactivity lately...moving my life 1600 miles on a weeks' notice |
| 49 |
hasn't exactly been the easiest thing, definitely hasn't helped for |
| 50 |
the free time column. |
