[Bug 95686] Re: [needs-packaging] Dolda Connect

2009-03-27 Thread sn00p 
No changes with this request? The program is complicated and includes
different daemons, shell and lisp scripts and even python module.
Nevertheless I've just fully debianized it.

[Bug 293026] [NEW] Grub install problem during 8.10 installation procedure on huge disk volumes.

2008-11-03 Thread sn00p 
Public bug reported:

Ubuntu 8.10 server edition normal install. On a system with huge disk volumes 
over 2 TB with GPT table grub is installed by default by installer system. But 
grub can not handle devices with GPT table. 
Disk partitioning is correctly working and make GPT table in huge volumes but 
during installation procedure in normal mode you can not select grub2 instead 
of grub which could correctly work with GPT table. As a result kernel can not 
find root device. 
I think that adding a capability to select a grub2 package during installation 
procedure could help to handle this situation.
