 |
|
Hi,
I have a Gentoo on SDcard for ma RPi3. But for now i can't compile anything because it is full for / :
| Code: | | /dev/root 8689792 8210648 14692 100% / |
When i do an eclean-dist, i have this :
| Code: | | /dev/root 8689792 6748488 1476852 83% / |
Also, i rm all in /tmp/portage/.
My / is partionned to be around 8 Gb i was thinking it wil be sufficient.
I saved ~ 2 Gb but it is not sufficient !
My question is hy gentoo is so hungry and how to retrieve some space ?
Thanks. |

You can remove kernels that you no longer need from /usr/src.
/var/log can be cleaned of old logs. Do not remove /var/log/emerge.log as its a source of valuable information.

You can keep distfiles and portage on a server common for ALL your gentoo systems! 
This way I save several gigabytes of diskspace. |

| I keep only one kernel sources (i always test before i delete the older). It seems for me so curious that anyone of complete distro can be tight in less to 2 Gb. Why Gentoo takes so big ? |

Irre,
Indeed you can. I choose not to as I run a number of installs on several different ARCHs and I like to keep the installs self consistent.
I use http-replicator and my own rsync server to minimise the load on the servers.

If I did this on my central server I could junk http:replicater and not worry about internal syncs.
Do you have a link to a How To? |

Mouski,
A Gentoo install with easy stripping of sources, packages, the portage repository, distfiles, cleaned build space and logs, just about fits into 6GB.
That's how I install to my netbook 8G SSD.
I could remove the tool chain and make it smaller still.
You can save about 2G for your portage repository by using squashfs for it.
squashfs is a read only filesystem in a file.

Mouski,
There is the squashfs wiki guide
Unfortunately, you need to download the repository to squash it yourself.
The good news is that Gentoo provides the squashfs for you.
You still need kernel support for squashfs. That's covered in the wiki,
