Force a static link

configname: CONFIG_STATIC_LINK

Linux Kernel Configuration
└─>UML-specific options
└─>Force a static link
In linux kernel since version 2.6.12  
This option gives you the ability to force a static link of UML.
Normally, UML is linked as a shared binary. This is inconvenient for
use in a chroot jail. So, if you intend to run UML inside a chroot,
you probably want to say Y here.
Additionally, this option enables using higher memory spaces (up to
2.75G) for UML.

NOTE: This option is incompatible with some networking features which
depend on features that require being dynamically loaded (like NSS).
