cannot close file descriptor: input/ output error on built images

[JC Hulce]

When I use the ebuild script to build an iso, the resulting image will boot to a blank blue screen with a cursor. By pressing ctrl+alt+f1, you can see the error in a terminal. Trying to run any command results in the error "cannot close file descriptor: Input/ output error". This prevents the normal startup screens from displaying.

It has been reported that transforming an installed system into eOS with "conf.sh --configure-installed" may be a workaround.

'conf.sh --configure-installed' its actually not recommended, use it on your own risk.

[JC Hulce (soaringsky)]

the --configure-installed method works for me at customising the installed system, but for my application I need to generate an iso image, so it is not a full workaround.

Which image do you use as a base? Natty or Oneiric?

[Sergey "Shnatsel" Davidoff (shnatsel)]

Reported to appear on Natty.

[JC Hulce (soaringsky)]

I found this issue with natty. Does anyone know if it exists in Oneiric?

[Sergey "Shnatsel" Davidoff (shnatsel)]

Testing Oneiric right now.

[Sergey "Shnatsel" Davidoff (shnatsel)]

I actually had the blue screen issue in Oneiric, and only in Oneiric. In today's oneiric build it boots to the login screen and seems to hang there.

[Sergey "Shnatsel" Davidoff (shnatsel)]

JC Hulce: it seems to me that for your particular application you don't need eBuild at all. All eBuild is started because we need to copy some files to chroot automatically. In your case http://uck.svn.sourceforge.net/viewvc/uck/trunk/uck/docs/html/building-script.html will work much better, and it has WAY less bugs.

[JC Hulce (soaringsky)]

@ Sergey Davidoff I've tried UCK, and I ran into some bugs with it too. I need to customise the image, with things like the MOTD, Print test page, user, hostname, etc in addition to UGR package set.

[Sergey "Shnatsel" Davidoff (shnatsel)]

Hmm, it booted pantheon-wallpaper for me in VirtualBox with Oneiric base. With Natty base on LiveUSB I get the same error.
Will hack...

Revision 173 is not yet affected by this bug. I suspect this is because of our casper.conf sorcery.

[Sergey "Shnatsel" Davidoff (shnatsel)]

Yes, casper.conf tweaks were causing this bug. I've commented them out in revision 186. This particular bug is "fix released" now, but I'm opening a new bug for missing casper.conf tweaks.

UGR guys should simply remove all the casper.conf stuff, they don't need it.
