While embedding root-filesystems to create a live-USB using paqfs I found some interesting behavior :
Starting your user file server with
*argp++ = "userfsrv";
*argp++ = "-S" ;
*argp++ = "ufsrv" ;
*argp++ = "-f" ;
*argp++ = partition ;
for(i=1; i<bargc; i++)
*argp++ = bargv[i];
*argp = 0;
exec("/boot/userfsrv", arg);
fatal("can't exec userfsrv");
and using :
int nfd=open("#s/ufsrv", ORDWR) ;
return nfd ;
works, while using -i to connect over stdio (-pipes) does lead to a version error in devmnt
Using this method its quite simple to create a bootable USB (install-) live Stick from within 9legacy or 9vx.
I didn't have the time to search for the reason behind this changed behaviour in devmnt.
With this workaround I created a bootable install CD from the 9legacy ISO for devices which don't have CDROM devices.

extended info to my last post in this thread ...
the code fragments have to be placed in 9/boot/xxx.c while xxx.c is the name of your rootfile server file (paq.c embed.c ...).
