"Evaluate EXP in a QEMU virtual machine running LINUX with INITRD (a

|
|
|
|
derivation). In the virtual machine, EXP has access to all of INPUTS from the
|
|
|
|
|
store; it should put its output files in the `/xchg' directory, which is
|
|
|
|
|
copied to the derivation's output when the VM terminates.

|
2013-08-31 20:55:04 +00:00
|

|
DISK-IMAGE-SIZE bytes and return it.

|
|
|
|
|
|
When REFERENCES-GRAPHS is true, it must be a list of file name/store path
|
|
|

pairs, as for `derivation'. The files containing the reference graphs are
|
|
|
|
|
made available under the /xchg CIFS share."
