Re: Speed up installation: activate eatmydata-udeb by default and include eatmydata package in /pool
Hi.
I'm writing here to share my experience with eatmydata in the debian-installer.
I was installing Debian 10 on a USB stick. The PC has a USB 2.0 port
and the stick's writing speed is about 4.6 MiB/s. I did not measure
the installation time precisely, but I'm sure it took at least 6 hours
to complete
with an LXQt desktop and an Apache server.
I installed manually eatmydata, libeatmydata1 and eatmydata-udeb
on the installer's filesystem, by extracting the contents of the archives
to their right locations. I do not remember using anna-install to install
the udeb, I don't know if it would make a difference.
Also, I used the normal DVD-1 ISO image, without eatmydata in it.
I wanted debootstrap to be called with eatmydata from the installer's menu,
so I renamed debootstrap as "debootstrap1" and put along it a script called
"debootstrap" which does 'eatmydata debootstrap "$@"'. I made the patch
described at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=700633#50
but debootstrap complained that it cannot find eatmydata in the ISO, so I
installed it by hand, no apt, I don't know if this changed the
expected behavior.
Also, I don't know if using eatmydata explicitly with the script and later using
the scripts included with eatmydata-udeb cause some conflict and make it
not work.
I saw at the fourth virtual console that libeatmydata1.so was not being found
by the installer in the target directory tree, it was because I forgot
to make the
symbolic links pointing to the real library. I made it while the
installation was
already running and I stopped seeing the messages come out in the syslog;
I suppose it was detected later, but I don't know if it worked as it
should since
I did this at the middle of the installation process, not before.
Anyway, perhaps I did something wrong, these are the things I remember
I did not do as specified in the above message. But if everything
should have worked right, then eatmydata doesn't work as I expected
in my USB stick, or it is just too slow and it can not install faster.
What do you say?
Have a good day.
