Interesting Tip that I'll have to try (got 4GB) by doing a world rebuild. Will let you know how it works with kdeenablefinal in make.conf using monolithic builds instead of split packages. |
Openoffice might break it. I thought I read that Openoffice needs 5 gigs to build.

The ebuild actually checks for that and if it doesn't see that 5GB will error out the ebuild.

Do we still need to do this?
I notice that the more recent versions of portage support a envar called PORTAGE_TMPFS which by default points to /dev/shm, a notorious standard tmpfs location.
The wording in the make.conf.example (The only documentation I can find for this var!) makes it sound like emerge will use the tmpfs location pointed to automatically? |

not if you set that variable, just edit your /etc/fstab and you're good to go. |

Having TMP in Ram sounds like a great idea. Wouldnt it be way better though if portage supported this directly.
e.g, by having something like
RAMBUILD=Yes
RAMBUILDSIZE=1G
in "FEATURES" in the make.conf.
So basically portage should try to compile anything in ram as long as it fits into the size you determine, and if its too big, it automatically uses HD space. |

yes, but you still need to specify the RAM size in your /etc/fstab. |

Sorry, yeah I get that; I was replying to ChojinDSL's idea (As it already implemented \o/)
EDIT: Oh, wait, you actually HAVE to set a RAM size in fstab or it won't work...??
Because I just tried the PORTAGE_TMPFS= and it didn't do a thing...

Except it still doesn't intelligently avoid cases where the package would overflow allocated space. OpenOffice may check that 5g is available, but other ebuilds don't. It can't ever be a set it and forget it type thing until this is solved.
I think the ideal would be a special tmpfs that overflows into a directory or a growing file instead of swap. |

| nothing wrong with swap.. and if a package fails most people should just know to comment the make.conf variable to resume without tmpfs support. |

you will have to umount /dev/shm, edit fstab with size option then remount it for it to take effect. |

Swap is usually a lot smaller, and a lot of time can be wasted before you find out you'll need to restart. |

I have been using this tips. I have 3GB of RAM.
My /etc/fstab:
| Code: |
# tmpfs for for portage to compile in RAM.
none /var/tmp/portage tmpfs nr_inodes=1M 0 0
|
When do "df", I usually have 1.5GB of /var/tmp/portage
Today I finally tested the limit with the following package in portage. emerge was out of space for /var/tmp/portage.
x11-misc/openclipart
I had to umount /var/tmp/portage temporarily and let it uncompress on actual harddisk.
