We currently use ext2 for our shmfs, if we switch to minix we save at l= east another 1 MB. Any complains? I actually never used minix before, but I expect that it supports the "normal" file ownerships and permissions. cya Heiko = |

Yes, minix has a filename size limit of 14 or 30 characters (depending on format options). This will break applications that use longer filenames. > >I actually never used minix before, but I expect that it supports the > >"normal" file ownerships and permissions. > > Shit!

That could be a problem. :-) Would using ReiserFS save any memory over ext2? - BS |

I doubt it. The problem is that we need to have the correct mkfs.xxxx tool in our initrd. I'll check tonight how big the static binary is. Heiko = |

I have to check in the changes, I'll do that right now. Currently you have to disable the start of the grsecurity script, this blocks the whole system. cya Heiko = |

The problem are usually the programs we use. When they don't behave like they're officially allowed, grsec will give them a hard time. But it keeps hackers out.... I found the problem and it's corrected in CVS. Randomization of PIDs has to be disabled. Don't ask me why.... Heiko |
