20 GiB of free space?

[znavko]

Hello, dear Funtoo developers!

I want to ask about free space for debian-sources. Why 20GiB ?

# eix-sync
...
# emerge -auDN debian-sources

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  NS    ] sys-kernel/debian-sources-4.14.12 [4.8.15, 4.14.2] USE="binary" 

Would you like to merge these packages? [Yes/No] yes

peak size used by temporary directory where debian-sources compiling is about 17GB. 20GB is set in ebuild with some exceeding margin to ensure it's enough space.

If space is a problem you can work around this by redirecting your portage temp directory to a larger partition by adding this to your make.conf file.
