[gentoo-user] how to prevent ebuild from checking for available space

In this case, the offending package is dev-lang/rust, but this has 
happened to me previously with other packages that require a lot of 
space and time to build.

The build fails for any reason.  Since it has already progressed over 
half way through the build, I would like to continue the build instead 
of starting from scratch.  I fix whatever caused the issue.  In this 
particular case, it failed for out of space, so I added another G to the 
ramdisk mounted at /var/tmp/portageg.  I issue "ebuild 
path/to/package.ebuild compile" but it fails immediately because there 
isn't enough free space.  The problem is that it's checking for enough 
free space to do the entire build, not just to continue from where it 
left off.

I've done some searching, and found one old forum post which suggests to 
just temporarily remove the space check from the ebuild.

In this case, that seems to be line 236 of 
/usr/portage/dev-lang/rust/rust-1.75.0-r1.ebuild, which is 
"CHECKREQS_DISK_BUILD=${M}M check-reqs_pkg_${EBUILD_PHASE}" the last 
line withing pre_build_checks().  However, if I comment out that line, 
and run "ebuild path/to/ebuild manifest" another attempt to compile 
still gives the same error about not enough space.

Am I commenting the wrong line?  Have I missed something about where 
this check is atually done?  Is it actually possible to do what I'm 
trying to do?

Thanks for any pointers or suggestions.

Jack
