[Pkg-mono-devel] mono-xsp: Process has not been started.

[Chris Capon]

There is a solution to this problem but I believe a fix should be 
applied to the mono-xsp package (and possibly mono-apache-server).  User 
"www-data" does not have write permissions to it's home directory.

The original failure is caused by mono-xsp not being able to run the mcs 
compiler.

When launching mono-xsp from /etc/init.d, it is run as the default user  
set in /etc/default/mono-xsp which is "www-data".  This user is not able 
to launch the mcs compiler.  You can test this by "su www-data" and try 
to run mcs.

The executable mcs is in the search path, but it needs to create a 
folder called .wapi in the user's home directory for temporary files.  
The "www-data" user's home directory is /var/www for which it has no 
write permissions.

Either /var/www needs write permissions for user "www-data", or a new 
home directory must be assigned.

My solution was to create a folder /var/www/.wapi and set "www-data" as 
it's owner.  This allowed it to compile .aspx pages and everything 
worked again.
