[K12OSN] "umount: device is busy" error in ltsp-build-client

[Danilo Câmara]

So far I have successfully installed LTSP in Fedora 10 x86_64 servers
(for i386 thin-clients) but when installing on Fedora 10 i386 servers I
always get the following error message in ltsp-build-client:

  ...
  Installing: perl-Pod-Simple              ##################### [387/388] 
  Installing: hpijs                        ##################### [388/388] 

umount: /var/tmp/imgcreate-mDg5Ft/install_root: device is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))
/usr/share/ltsp/plugins/ltsp-build-client/common/010-chroot-tagging: line 3: /opt/ltsp/i386/etc/ltsp_chroot: No such file or directory
error: LTSP client installation ended abnormally

 
The best match I found on the Web about this is on
https://www.redhat.com/archives/fedora-livecd-list/2008-February/msg00120.html
but there was no conclusive solution there.


I am installing from the LTSP packages in Fedora 10 distribution and did
the following configurations:

diff /etc/ltsp/ltsp-build-client.conf.original /etc/ltsp/ltsp-build-client.conf
8c8
< # option_cache_value=/var/cache/chroot
---
> option_cache_value=/var/cache/chroot
10c10
< # option_arch_value=i386
---
> option_arch_value=i386
 

and these configuration to use our local network mirror of the packages
(downloading from web I got the same results)

diff /etc/ltsp/kickstart/Fedora/10/ltsp-i386.ks.original /etc/ltsp/kickstart/Fedora/10/ltsp-i386.ks
